Answer 2

Answer:

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
