Question

A bullet of mass 20 gram is horizontally fired with velocity 150 M per second from a pistol of mass 2 kg. what is the recoil velocity of the pistol ?​

Answer 1

Mass of bullet*velocity of bullet=mass of pistol*velocity of pistol

i.e.0.2*150=2*recoil velocity (20 gram=0.2kg)

i. e. recoil velocity =(0.2*150)/2=15m/s
