Question

A bullet of mass 20 gram then fired from a gun with the velocity 150 metre per second if the mass of gun is 2 kg, find its recoil velocity

Answer 1

mass of bullet,m = 20g = 0.02 kg

its velocity v = 150 m/s

mass of gun,M =2 kg

recoil velocity = -(m/M) X V

                        =(0.02/2) X 150

                       = O.O1 X 150 = 1.5 m/s
