Question

A machine gun of mass  fires  bullets at the rate of  bullets per minute with a speed of  each. The recoil velocity of the gun is :

Canvas Classes · Accepted Answer

🧠 Recoil — Total Bullet Momentum Per Second Equals Gun's Momentum Per Second

Read the question. A  machine gun fires  bullets at ,  bullets per minute. We want the gun's recoil velocity.

This is conservation of momentum applied in one second. In one second the gun fires  bullets. The total momentum carried forward by those bullets must be balanced by the momentum the gun carries backward (since the system started at rest).

First concrete move: find momentum carried by bullets in , set the gu
