Question

what is recoil velocity

Answer 1

Recoil velocity is the speed with which the rifle or pistol recoils when the bullet is fired. If the gun bullet and the gun mount were frictionless the equation bullet mass times bullet acceleration equals gun mass times gun (recoil) acceleration if you ignore the powder for the moment.

Answer 2

recoil velocity is the recoil momentum divided by the mass of the recoil body. The recoil momentum is equal to The momentum of the other body. The momentum of the other body is equal to the its mass times its velocity.
