Question

A bullet of mass 0.02 kg is fired from a gun weighing 7.5kg if the initial velocity of bullet is 200m/s calculate the recoil velocity of the gun

Answer 1

According to Law of Conservation of ,momentum :

Mass of bullet x velocity of bullet = Mass of gun x recoil velocity of gun

0.02 x 200 = 7.5 x recoil of gun

Recoil of gun = 0.02 x 200/7

Hope it helps
