Question

A machine gun has a mass of 20 kg. It fires35g bullets at a rate of 400 bullets per second with a speed of 400 m/s. What force must be applied to the gun to keep it in position?​

Answer 1

Hello ,  

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 = Bullet mass * velocity * rate/second  

=0.035 * 400 * 400/60  

= 93.333 newton

Hope This Helps.
