Question

A machine gun fires 25 g bullets at the rate of 600 bullets per minute with a speed of 200 m/s. Calculate the force required to keep the gun in position.

Answer 1

The rate of bullets per minute = 6000 per minute
= 6000/6 per sec
=10 bullets per sec
as we know
F=n * m * v
=10 . 200 . 25 .10^-3
= 2N
