Answer 1

Explanation:

velocity The rate of a body's motion in a given direction per unit of time; speed Ballistics The speed that a projectile/bullet attains while in flight; the difference in tissue destruction between high- or low-velocity bullets is caused by the fragmentation of the bullet–as occurs in an M-16 semiautomatic weapon, rather than the speed of the bullet. See Ballistics, Critical velocity.
