A machine gun fires a bullet of mass 40 ...

A machine gun fires a bullet of mass 40 gm with a speed `1200 m//s` The man holding it can exert a maximum force of 144 N on the gun. How many bullets can he fire per second at the most?

A

One

B

Four

C

Two

D

Three

Text Solution

Verified by Experts

The correct Answer is:
D
`F=(dp)/(dt)=d/(dt)(nmv)=mv(dn)/(dt)`
`:. (dn)/(dt)=F/(mv)=144/(40xx10^(-3)xx1200)=3`
