Question

Machine gun fires 40 Gmail bullets at a speed of 1 km/s. The gunner holding the gun in his car exerts an average force of 160 N against the gun. Find the maximum number of bullets he can fire per minute

Answer 1

Answer:

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
