Question

Define recoil velocity. define expression for it also

Answer 1

Answer:

It would always be negative as the gun will always move in the opposite direction of the fired bullet.

The recoil velocity is the result of conservation of linear momentum of the system.

When you fire a gun, momentum is conserved. 0+0=m1v1*+MV where v1*=speed of bullet and V is the recoil velocity of the gun.
