A machine gun...

Question

A machine gun fires 60 bullets per minute with a velocity of 700m/s . If the mass of each bullet is 50g , calculate the power of gun .

Open in App

Solution

Each bullet will have KE = 1/2 * 0.05 * 700 * 700 = 12250 J
So for 60 bullets the energy given by machine in 60 second = 60 x 12250 J
Hence power developed = Energy / time = 12250 W
Or power = 12.250 kW.
