Answer to Question #246245 in Mechanics | Relativity for Meo

Question

A machine gun Fires 50gm bullets at a speed of 1000m/s. The gunner, holding the machine gun in his hands, can exert an average force of 180N against the gun. Determine the maximum number of bullets he can fire per minute

Answer 1

It is the impulsive force so...

$I=mv$

=50×10^-3kg×1000=50

If man can hold the gun at a recoiling force of 180N so in 1 min

180∗60=10800

$No. Of bullets per min =\frac{ force * time }{impulse control}$

$= \frac{10800}{50}$

= 216
