From a gun of mass 4 kg, a bullet of mass 40g
is fried with inital velocity of 35ms-1

​

Answer 1

Explanation:

Given : m=40 g =0.04 kg v=1200 m/s F=144 N

Let n be the number of bullets that can be fired per second.

The force exerted by man must balance the change in momentum of the bullets per second.

∴ F=mnv

OR 144=0.04×v×1200 ⟹n=3 bullets per second
