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

A

60 mnv

B

`(60v)/(mn)`

C

`(mn v)/(60)`

D

`(mv)/(60n)`

Text Solution

Verified by Experts

The correct Answer is:
C
F = rate of change of linear momentum
In 1s, `n/60` bullets are embedded. Momentum of each bullet is mv
`therefore F=(n/60)mv`
