Q. A machine gun has a mass of $15 kg$. It fires 100 gram bullets at the rate of 40 bullets per minute at a speed of $600 m / s$. What force is required to keep the machine gun in position?

Laws of Motion

Solution:

Force $=\frac{\text { momentum of bullets } \times \text { no. of bullets }}{\text { Time }}$
$=\frac{0.1 \times 40 \times 600}{60}=40 N$
