Question

Sir/Mam

A gun weighing 10 kg fires a bullet of 30 g with a velocity of 330 m/s . With what velocity does the gun recoil ?

Pls help me solve this question

Thnx

Answer 1

Momentum of the bullet equals the momentum of the gun.

Momentum equals to : Mass × Velocity

We substitute into the formulae and get :

0.03 × 330 = 10 × V

9.9 = 10V

V = 0.99 m/s

recoil velocity=0.99 m/s

Hope this answer will help you.
