Question

find out recoil velocity of bullet fired from rifle​

Answer 1

It's now easy to calculate the recoil speed of the rifle (vR)in feet/second: vR = -(mB ÷ mR) vB = -(9.72 g ÷ 3,632g) • 2,820 ft/s = -7.55 ft/s. The minus sign denotes the fact that recoil speed is in the opposite direction to the speed of the bullet.
