How much kinetic energy to kill a deer.

A 2.0-kg object moving with a velocity of 5.0 m/s in the positive x direction strikes and sticks to a 3.0- kg object moving with a speed of 2.0 m/s in the same direction. What is the final velocity of these two objects? How much kinetic energy is lost in this collision? 2. An 80-g particle moving with an initial speed of 50 m/s in the positive x.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.Jan 12, 2014 · 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. The impact forces in an auto collision are much smaller than the needle, but that car collision may well kill. Momentum and energy are much important concepts than force. Which of momentum or energy is more important depends on the circumstances. ... (determining the kinetic energy of the object at impact e.g. a 10kg mass falling from 1m has 10 ...How much kinetic energy should I look to achieve out of my arrows for deer hunting? From: Bou'bound. ... 05-Sep-12. deer are not that hard to kill. I hunt with a recurve that gets about 30 foot pounds of energy. Killed two deer last year with it one doe was at 30 yards which is at my max and I did not get a pass through she feld dressed out at ...

Falling, mines, car bombs, trap doors, extreme pressure, slow squashing, and tearing apart all use kinetic energy to kill so they don't apply. Poisoned needles, drowning, burying, hanging, tying up, and rolling up in a carpet are practically impossible to inflict against a person of superhuman toughness and reflexes.The kinetic energy formula defines the relationship between the mass of an object and its velocity. The kinetic energy KE equation is as follows: KE = 0.5 × m × v². where: m — Mass; and; v — Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object.

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 ...A lot of people consider 1000 ft/lbs of kinetic energy to be the minimum amount of power to humanely kill a deer. If you believe this, then the yardage to make this shot is dependent on your load and velocity. The chart I attached figures a 142 grain bullet with a MV at 2700 (which is a pretty conservative speed).

To calculate Kinetic Energy we can use the following basic formula. KE = .5Mass x Velocity². For bowhunters, we can take the total weight in grains of our arrow as Mass. Velocity can be speed of the arrow in feet per second. The final equation to calculate your arrow's KE will be. KE = (Mass)x (Velocity x Velocity)/450,800.When hunting for big or small game, we need to look at the pellet's weight multiplied by the Velocity Squared, divided by 450395. Conventional wisdom has held that 1,000lbs foot-pounds of energy are required to kill a deer. However, users of the Umarex Hammer are easily killing big game as large as cape buffalo with a 550-grain bullet ...By Bob Robb. When discussing the penetrating ability of a hunting arrow, the two most commonly referred to factors are kinetic energy and momentum. The term kinetic …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 / ...

In order to be successful in taking down a deer you need to have a bow that is properly sized for the game you are hunting. As a general rule you will need at least 40 pounds of draw weight to kill a deer. This means that the bow must be able to pull back the arrow with enough force to penetrate the animal’s hide and reach the vital organs.

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 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. See moreThe minimum caliber for deer hunting varies by state, but it is generally recommended to use a caliber of .243 or higher. Can a 5.56 kill a deer at 300 yards? While it is possible for a 5.56 to kill a deer at 300 yards, its effectiveness at that distance may not be as reliable as larger calibers. Is 5.56 lethal enough for deer hunting?For example, any given body has kinetic energy if it is in motion. A tensioned device such as a bow or spring, though at rest, ...

How many feet per second does it take to kill a squirrel?An explosion causes an object, initially at rest, to break into two pieces. One of these pieces has twice as much kinetic energy as the other. What is the ratio of their masses? Which one has the larger mass? Is it the one with the larger kinetic energy, or the one with the smaller kinetic energy? All I want to know is what kinds of Physics ...

Those weighing 20-35 lbs require 35-50 foot-pounds of energy to kill, and those weighing 50-75 lbs require 80-100 foot-pounds of energy. Large game refers to animals over 75 lbs. Animals weighing up to 500 lbs require 150-250 foot-pounds of energy to kill. While animals around 1000 lbs or more require 500-700 foot-pounds of energy to kill.Normally a conical is fired at velocities between 1,200 and 1,600 feet per second (fps). A 370-grain .50-caliber conical with a 100-grain charge will have a velocity of about 1,450 fps. The muzzle energy of such a load is 1,727 ft./lbs., but at 100 yards, only 825 ft./lbs. My .58-caliber 260-grain round ball with a 100-grain blackpowder charge ...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 ...How much kinetic energy is released in this explosion? A 6.0 kg object, initially at rest in free space, "explodes" into three segments of equal mass. Two of these segments are observed to be moving with equal speeds of 20 m/s with an angle of 60 degrees between their directions of motion.The cartridge you pick depends a lot on how far you will shoot. If the cartridge can deliver a hunting-weight bullet of at least 100 grains to the target with 1,000 ft-lbs of energy, then it's a fine cartridge for the job. Anything from the .25-06 Remington through the various .300 magnums will work for long-range deer hunting.Create a free account to view solutions. Find step-by-step Physics solutions and your answer to the following textbook question: An internal explosion breaks an object, initially at rest, into two pieces, one of which has 1.5 times the mass of the other. If 7500 J were released in the explosion, how much kinetic energy did each piece acquire?.From the muzzle too 100 yards, the 7.62×39 brings a pretty significant more amount of kinetic energy than the 5.56×45 rounds. And again, it is interesting to compare these two cartridges as the rounds move past the 100 yard mark. As they continue, the 7.62×39 rounds tend to lose energy at a much higher rate than the 5.56×45 rounds.

The unofficial rule regarding minimum KE to push an arrow through a deer is about 40 foot-pounds. Lower-poundage bows are slower than higher-poundage models. So, let’s say the bow is pushing a 350-grain arrow at 265 feet per second. That setup is delivering roughly 54 foot-pounds of KE and .411 slugs of momentum.

Kinetic Energy & Momentum Calculator. Find out the kinetic energy of your arrow or bolt using the following simple calculator. Your kinetic energy is [ field2 * (field4 * field4) / 450240 ] foot pounds, and your momentum is [ field4 * field2 / 225400 ] slug FPS.

See 3,000+ New Gun Deals HERE. FAQs about Kinetic Energy Levels for Deer Hunting with Bows. 1. What is kinetic energy in bow hunting?Those elements are what is needed to calculate kinetic energy. For example, my bow fires a 400 grain arrow (broadhead included) at 305 feet per second. To find the kinetic energy, I multiply 305 by 305, then multiply by 400. I get 37,210,000. Divide that by 450,240 and the kinetic energy is 82.64 ft. lbs. I suggest using a calculator.Dec 1, 2012 · To score an instant kill with the usual deer rifle, exact bullet placement is required in a vulnerable area. The required degree of bullet placement will vary almost directly in proportion to the size and life tenacity of the animal, but will be somewhat inversely proportional to the striking energy and momentum of the bullet provided that expansion and penetration are uniformly balanced. Jan 30, 2011 · I have seen recommendations of 45# for deer and 55# for elk if using fixed blade broadheads. If using mechanicals 55# for deer and 65# for elk. I think both of these are on the high side. I have a female customer killing deer consistently with 33# of KE and using Rage KE's. PASSTHRU ARCHERY - 828-273-2815. But energy is a rough estimate of killing power only so long as you are comparing two reasonably similar calibers and bullets in terms of sectional density. Compare a 200-grain bullet fired from a .35 Remington rifle to the same bullet fired from a .350 Remington Magnum and you’ll find that the magnum’s bullet carries more energy to the ...For example, any given body has kinetic energy if it is in motion.

Two of these segments are observed to be moving with equal speeds of 20 m/s with an angle of 60 degrees between their directions of motion.A 1 ms smack requires more acceleration to kill you than a 100 ms smack. Penetrating injuries to the head have a good chance of killing you. The army long used 58 ft-lbs as the energy of a projectile (bullet or fragment) needed to cause a casualty, but that just assumed a hit and not necessarily a hit to the head.For deer hunting, it is recommended to have a ballistic energy of at least 1,000 foot-pounds to ensure a clean and ethical kill. 1. What is ballistic energy? Ballistic energy is the measure of a bullet’s ability to penetrate its target. 2.For example, having 1,500 ft-lbs of energy to kill a bull elk is a decent barometer, but elk have also been killed with far less energy when excellent shot placement and good bullet construction are in play. ... If …If the average person can punch at a 15 mph and v is in meters per second this means a punch is moving ~6.7 mps. This gives that punch 45j. Now the average man in the USA weighs about 200 pounds and the average male arm makes up 5.7% of the body. This gives the arm 11.4 pounds which is ~5.2 kg. That would give a punch force of 116j.Doesn't take much to kill a deer at 30 yards. Well tuned bow/arrow, good foc and sharp cut on contact broadhead as well as shot placement will determine success. Sent from my DROIDX using Tapatalk 2 . AT motto,if you can't dazzle em with brilliance,baffle em with BS :darkbeer:Speed is a component in the equation, but mass affects MO and penetration much much more over speed. You will kill a deer with an arrow flying 50fps if it weighs 700, 800, 1000 grains, I don't know that number. I would be willing to bet you could get a PT at 10 yards. ...
