[QUOTE="Mike375, post: 51606, member: 227"] If a bullet has 3000 ft/lbs of kinetic energy, than that is sufficient energy to lift a 3000 pound weight by a height of 1 foot or a 1 pound weight by a height of 3000 feet or a 200 pound weight by 15 feet etc. Energy is "work" and power is the rate at which work is done. So the bottom line is that the bullet does have enough energy to lift the deer 15 feet. However the energy is not released in the right way for this to happen. It is kind of like "gearing". If we could somehow attach a very (very very [img]images/icons/grin.gif[/img]) long string to the bullet and that string was wound around a pulley or drum and then the pulley was geared way down, then the final pulley at the end of the gearing could be used to wind up a 200 pound deer. If the gearing was right and there were no losses from friction, then the deer would be lifted 15 feet before the bullet stopped. If we now let the deer fall back down and the gearing system was still in place, then when the deer hit the ground, the bullet would have of course been wound back by the string and "presto" it would be back at its muzzle velocity and the deer would be at rest Mike [/QUOTE]
