A machine gun fires 360 bullets per minute and each bullet with a velocity of 600 msec-1

. It

the mass of each bullet is 5gm. Find the power of the machine gun.​

Answer 1

Answer:

power of gun = no of bullets fired in 1 sec × kinetic energy of each bullet

5.4 ×1000 = 360/60 × 1/2 m (600)^2

m = .5 ×10^-3 kg

m = .5 g
