Answer:

After firing the bullet, the bullet moves forward with a large momentum and the gun moves backward with an equal momentum. Let m and M be the masses of bullet and gun, respectively. If v and V are the velocities of the bullet and gun, respectively after the firing then:- 0= mv+ MV Therefore V=-mv/M The negative sign indicates that the gun moves in a direction to that of the bullet.
