Question

A bullet of mass 100 gram is fired with a velocity of 150 m/s from a pistol of 2 kg mass. What is the recoil velocity of pistol?​

Answer 1

This question can be easily done by conserving the momentum of pistol and bullet.

Magnitude of momentum of bullet= Magnitude of momentum of pistol

0.1 * 150 = 2V

V= 15/2 m/s
