A machine gun fires a steady stream of bullets at the rate of n per minute into a stationary target in which the bullets get embedded. If each bullet has a mass m and arrives at the target with a velocity v, the average force on the target is :
- 60 mnv
- \(\frac{60 \mathrm{v}}{\mathrm{mon}}\)
- \(\frac{\text { mav }}{60}\)
- \(\frac{m v}{60 n}\)
Answer
(C) mav 60
