Question

A machine gun has a mass of 20kg. It fires 35g bullets at a rate of 400 bullets per second with speed of 400m/s. what force must be applied to the gun to keep it in position?
(P.S.- the answer is not 93.33333N)​

Answer 1

Here,Mass Of Machine Gun(m)= 20kg

Mass of each Bullet, (M)=35g=0.035kg

Velocity Of Bullet(v)=400m/s

No.Of Bullets/sec=400/60=20/3

Force required = rate of change of linear momentum of bullets=n(mv)/t

=20/3×(0.035×400)/1=93.3N

Answer 2

Answer:

THE ANSWER IS ACTUALLY 93.3 N
