n bullet strikes per second elastically on wall and rebound then what will be the force exerted on the wall by bullets if mass of each bullet is m:-

A machine gun of mass M fires n bullets per second .The mass and speed of each bullet is m and v respectively. Then force exerted on the machine gun is :

A disc of mass 5 kg is kept floating horizontally in mid air by firing 10 bullets per second vertically up. If the mass of each bullet is 50 gm and bullets rebound with same speed, the speed of each bullet is, (g = 10 ms^(-2) )

A disc of mass 5 kg is kept floating horizontally in mid air by firing 10 bullets per second vertically up. If the mass of each bullet is 50 gm and bullets rebound with same speed, the speed of each bullet is, (g = 10 ms^(-2) )

A gun fires N bullets per second, each of mass m with velocity v. The force exerted by the bullets on the gun is :

A gun fires N bullets per second, each of mass m with velocity v. The force exerted by the bullets on the gun is :

A gun fires N ' bullets per second,each of mass m with velocity v .The force exerted by the bullets on the gun is

A machine gun fires n bullets per second and the mass of each bullet is m. If v is the speed of each bullet, then the force exerted on the machine gun is

A machine gun fires n bullets per second and the mass of each bullet is m. If the speed of the bullet is upsilon then, the force exerted on the machine gun is:
