feet to meters. A foot is 0.3048 meters, so 3,000 ft/s equals 3,000 * 0.3048 = 914.4 meters per second. 52 grams equals 0.052 kg. Replacing m and v in the formula we get KE = 0.052 · (914.4)2/ 2 = 21.7393 kJ or about 16,034 ft-lbs for the kinetic energy of the bullet....
The velocity mainly determines the amount of kinetic energy possessed by the bullet, as reflected in the formula for the energy of an object by virtue of its motion: E=1/2m×v2 where E is kinetic energy, m is mass, and v is velocity. Because bullets possess most velocity at the point...
