How much kinetic energy to kill a deer.

The average deer weighs between 150 and 300 pounds so it takes a lot of force to kill one. Depending on the size of the deer it takes between 1.5 and 3.0 foot-pounds of energy to kill a deer. This means that it takes between 12 and 36 inches of penetration to kill a deer. How many Joules of energy are required to kill a deer?3,567. Location. Falls Church, VA. Sep 12, 2010. #3. Although I agree with bigngreen that 1000lbs of energy and a well placed shot will take elk, the conventional wisdom says you need 1500 pounds of energy. So I ran your load in exbal and found that you have 1500lbs of energy at 500 yards and 1000lbs at 800.I've always suggested using Energy (lbs) thats (4 x the animals weight). Example a 200 pound deer needs 800ft.lbs. energy. deer: 700-1400lbs. "Energy". Elk: 1400-2000lbs. of course there is lots of varibles but this is a good rule of thumb.The muzzleloader has 2,680 ft.-lb. of energy at the muzzle and only 1,180 ft.-lb. at 200 yards. At 243 yards, the bullet falls below 1,000 ft.-lb. of energy—the widely accepted minimum needed to ethically kill whitetail deer. Wind Drift. With even a 10 mph wind, the 250-gr. Barnes will drift 10.91 inches at 200 yards.A commonly accepted threshold for the minimum amount of kinetic energy needed to kill an elk is 1500 ft-lbs. For whitetail deer, the minimum amount of kinetic energy is 1000 ft-lbs. We’ve all probably heard stories of hunters taking elk with a .243 Win.

Science. Physics. Physics questions and answers. During an ice skating performance, an initially motionless 88.5-kg clown throws a fake barbell away horizontally. The clown's ice skates allow her to recoil frictionlessly. If the clown recoils with a speed of 0.495 m/s and the barbell is thrown with a speed of 7.5 m/s, what is the mass, in ...An air-track cart with mass m1=0.34kg and initial speed v0=0.85m/s collides with and sticks to a second cart that is at rest initially. If the mass of the second cart is m2=0.55kg, how much kinetic energy is lost as a result of the collision? Express your answer to two significant figures and include appropriate units.An air-track cart with mass m1=0.28kg and initial speed v0=0.80m/s collides with and sticks to a second cart that is at rest initially. Part A If the mass of the second cart is m2=0.53kg, how much kinetic energy is lost as a result of the collision? Express your answer to two significant figures and include appropriate units.

In addition to reaching the target, the bullet should also strike it with a certain amount of kinetic energy in order to “achieve the desired effect” – i.e. neutralizing a threat or humanely killing a deer, respectively. You want your bullet to hit a threat with at least 220 to 300 ft lbs of kinetic energy.

The minimum kinetic energy needed to bow hunt whitetail deer is 25 ft-lbs. This is the absolute minimum. Compound bows with a draw weight of 40 lb generally put out a 240-grain arrow with 30 ft-lbs of kinetic energy. To increase kinetic energy you can increase draw weight or arrow weight.21 yrs. as a lodge owner/10,000 customer shots fired/ 7,100 deer/hog kills-speed+shot placement (shoulder)+correct bullet type=dead animal. Lots having guided elk, deer, bear, and goat hunters for 20 years I prefer lead bullets of heavier weight in magnum caliber. Ultra mags 338 ect have too much recoil for the average hunter.As I understand it, it assumes pretty much perfect headshot placement. 1) Gray squirrel/Fox Squirrel - 4.5fpe. 2) Eastern Cottontail/Swamp Rabbit - 4fpe. 3) Jack Rabbit White, Black, and Jack O' lope - 4.5fpe. 4) Raccoon/ Bandit - 9fpe.. if it's a big one, 10fpe. 5) Virginia Opossum/ County Rat - 10fpe.The average deer weighs between 150 and 300 pounds so it takes a lot of force to kill one. Depending on the size of the deer it takes between 1.5 and 3.0 foot-pounds of energy to kill a deer. This means that it takes between 12 and 36 inches of penetration to kill a deer. How many Joules of energy are required to kill a deer?

Having shot deer (120-150lbs) with both a .223 and a thunderhead at about 330fps through the lungs and heart I have to say the 3 with the bow didn't take more than five steps, where the two by rifle ran about 10 yards. I understand that the anatomy of deer and humans is different, but the overall size is somewhat similar.

I do ascribe to the 1500 ft-lbs delivered energy for Elk but the 2500 ft-lbs is perhaps now disproven for moose. In my opinion, deliverd energy should at least be 1500 ft-lbs or greater, ideally in the 2000 ft-lb range. After the shot, immediately reload and prepare to shoot again. The key to remember is to try for broadside shots whenever ...

Regenerative braking is a highly efficient process. Check out HowStuffWorks for information about how regenerative braking works. Advertisement ­ Every time you step on your car's ...Kinetic energy equals velocity squared, multiplied by mass, divided by 450,240. The sum equals the kinetic energy — a.k.a. KE in foot pounds — of an object in motion. ... Just as you can cleanly kill deer with a .22 Hornet, you can also kill elk with wide-cutting mechanicals and light arrows — if everything proceeds according to script ...In an inelastic collision, energy is lost to the environment, transferred into other forms such as heat. In the above figure, two objects A A and B B with the same mass m m are 15 15 m away from each other. Now, A A and B B are thrown horizontally at the same time at the velocities 20 20 m/s and -10 −10 m/s, respectively, eventually colliding ...Assume the deer remains on the car. 27. ... How much kinetic energy is transferred to the rifle-shoulder combination? The pain is related to the amount of kinetic energy, which is significantly less in this latter situation. (e) Calculate the momentum of a 110-kg football player running at 8.00 m/s. Compare the player's momentum with the ...placed. 2500 ft/lbs is recommended for animals weighing 1500 pounds and 4000 ft/lbs + for. dangerous game for obvious reasons. The main thing is to use a bullet at or above it's designed velocity and energy so as to get the. best performance from it under ALL hunting conditions. So to sum it up if you are hunting deer.

The effective range for a crossbow is the same as most compound bows: 40 yards. This is the distance over which the majority of bowhunters can repeatedly make a successful lethal shot. Much of this depends on accuracy. It's difficult to hit the kill zone the farther away the target is.Jun 2, 2023 · The minimum fps (feet per second) needed to kill a deer with a crossbow is between 250-400 fps. This range provides the necessary kinetic energy to penetrate the hide and reach vital organs of the animal, resulting in an ethical and humane kill. It is important to note that higher speeds can cause too much tissue damage, which should be avoided ... Dec 11, 2017 · In hunting, how much damage a bullet does is more important than its toughness. A bullet that sheds weight and deforms chaotically causes more damage. Conventional mono-metal bullets dump about 50% of their energy in the first 8 inches. Traditional cup-and-core and lead core dump about 80%. Somewhere along the way, the notion that you can ... So, when a net amount of work is done on an object, the quantity 1 2 m v 2 —which we call kinetic energy K —changes. Kinetic Energy: K = 1 2 ⋅ m ⋅ v 2. Alternatively, one can say that the change in kinetic energy is equal to the net work done on an object or system. W n e t = Δ K.The four major factors that influence penetration are Kinetic Energy, Broadhead Type, Friction, and ... a 400 grain arrow traveling at the glacial speed of 170 feet-per-second has sufficient energy to harvest a mature deer. Heck, many kids bows can easily shoot such a light arrow faster than 170 fps, and I’ve seen such rigs do pass-throughs ...Kinetic energy is physics ke=.5 x mass x velocity squared. For shooting we have to add in the acceleration due to gravity to convert from weight to mass and convert from grains to pounds so the formula becomes Ke= grains x velocity squared/ 2 x 7000 x 34.17 The 34.17 is relative to lat/long and elevation but that number is the accepted one to use. I dont understand how a cartridge could reach ...The 308 Win's .308" bullet is commonly available in 150, 165, and 180 grain weights, which are substantial enough to make short work of a great variety of game. In experienced hands it can hit a 1,000 yard target. Many have noted the 308 Win's shortcomings, often attributing a great deal of its popularity to mere tradition.

Choose your crossbow to shoot your hunting arrow with an initial velocity of a minimum of 250 to 300 FPS (Feet Per Second). By producing that speed, the arrow will get enough kinetic energy to kill any big game animal cleanly and also eliminates the long-range arrow trajectory problem. Weight. Choosing a crossbow based on weight is never easy.

The Spot You Need To Hit. With a quality bullet or slug, you can kill a broadside deer in its tracks by shooting through the near-side shoulder and into (or through) the off-side shoulder. And if you have the skills, gear and time to be extra precise in your shot placement, hit a bit high in the shoulder.At 50 yards downrange, a typical .357 Mag. bullet is traveling about 1,100 feet per second. That is 750 mph. Despite its power, recoil is more manageable with the .357 Mag. than with the .44 Mag., as the latter requires a bit of masochism if you are to enjoy even a half-hour shooting session.The muzzleloader has 2,680 ft.-lb. of energy at the muzzle and only 1,180 ft.-lb. at 200 yards. At 243 yards, the bullet falls below 1,000 ft.-lb. of energy—the widely accepted minimum needed to ethically kill whitetail deer. With even a 10 mph wind, the 250-gr. Barnes will drift 10.91 inches at 200 yards.Whatever distance you are shooting at, you need to remember that your arrow needs to maintain enough kinetic energy to penetrate the deer. (All of these distances assume that you are using a 400-460 grain crossbow arrow – the most suitable for hunting deer.) High-end crossbow (e.g. Ravin R500) of 450 – 500 FPS: 100 yards.Seems the answer is 1300 KE when the round hits the deer. That's not at the muzzle. I don't see any PCP rifles that are any where close to that. I know people are taking deer with thier PCPs. Arkansas law says, "40-caliber, produce at least 400 ft. lbs. of energy". Guess that's a start.Temperature is directly proportional to the average kinetic energy of the molecules in a substance. If the degree of motion of the molecules inside an object doubles, the temperatu...Speed alone is not a good indicator of a bows ability to harvest an animal. The question you should be asking is "how much kinetic energy do I need to humanely harvest a deer?" The general answer to that is something around 45 ft/lbs. Kinetic energy is a factor of the speed and weight of the arrow. The amount of KE produced is easily …

From there, a simple formula reveals the precise energy: Velocity (fps) x Velocity (fps) x Weight (grs.) divided by 450,240 equals Energy (ft.-lbs.). For example, let's say you shoot 500-grain arrows at 250 fps. Using this formula, 250 x 250 x 500 divided by 450,240 equals 62.47 ft.-lbs.A railroad car with a mass of 40,000 kg is going east at 3.0 m/s when it collides with a second car whose mass is 25,000 kg and is going east at 1.0 m/s on the same track. If the two cars couple together, how much kinetic energy was lost at the collision?5.0x10 to the fifth J, 7.3x10,1.8x10,3.1x10, 940 Jplease show the steps:)Cartridges that deliver 1,000 foot-pounds of energy are sufficient on deer species because they are smaller, thin-skinned and have a much lighter skeletal structure. The general consensus is that for a broadside shot on an elk you need 1,200 foot-pounds of energy and at least 2,000 foot-pounds for any quartering shot.25-41 Lbs KE.....Medium Game, Deer, Antelope. 42-65 Lbs KE .....Large Game, Elk, Black Bear, Boar. > 65 Lbs KE.....Toughest Game, Grizz, Cape Buffalo.The killing power of an arrow is measured in Kinetic Energy. Think of it as the force behind the arrow that drives it. More force equals deeper penetration. ... the minimum KE required for deer-sized game is 25 pounds. Most modern bows with at least a 30- to 40-pound draw weight and a 24-inch arrow can achieve that. ... A stand over 15 or so ...Kinetic Energy is important for all bow hunters as it is the amount of killing power or hitting power our arrows hit the target with. Different areas have guidelines about the minimum kinetic energy needed to take big game animals. As a general rule of thumb for medium sized game such as deer, goat, antelope, and sheep, 40 ft-lbs. of Kinetic ...Colorado. Oct 1, 2014. #9. I agree with what has been said, and also use a ballpark of 1500 ft*lbs as a minimum energy for elk. Although, I have never had the opportunity to test 1500 ft*lbs. My furthest shot on an elk still carried over 1850 ft*lbs at 630 yards with a barnes .338 210 gr TTSX.Kintetic Energy Formula. The formula for K.E. as measured in ft./ lbs. is: Mass x Velocity-squared divided by 450,240, with Mass the total arrow weight and velocity is the arrow speed. So let’s say you have an arrow that weighs 400 grains that flies at a speed of 290 feet per second. Your equation would look like this: 290 x 290 x 400 / ...Question: 21.
