A machine gun fires n bullets per second with speed u, and mass of each bullet is m. If bullets hit a wall and rebounds with same speed, then force acting on the wall 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:

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 each of mass m . If the speed of each bullet is v, then the force of recoil 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 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 :
