What is the velocity of recoil of a gun, if a bullet of mass 100 g is fired from a gun of mass 20 kg with a velocity fo 100 ms–1?
0.5 ms-1
Mass of bullet, m = 100 g = 0.1 kg
Velocity of bullet v = 100 ms–1
Mass of gun, M = 20 kg
Let recoil velocity of gun = V
V = -100×0.120 = -0.5 m/s
recoil velocity is 0.5 m/s
