Why does a heavy rifle not kick as strongly as a light rifle using the same cartridge?

Answer:

                Recoil velocity of a rifle, \[\vec{V}=-\frac{m}{M}\vec{\upsilon }\]              i.e., \[\vec{V}\propto \frac{1}{M}\] Thus the recoil velocity of the heavy rifle is smaller than that of the light rifle, so it does not kick strongly.
