A gun is mounted on a platform fitted with frictionless wheels. The mass of the platform With the gun, shells and the operator is M. The gun.fires shells one after another with a velocity v in the horizontal direction. If mass of each shell is in, show that the velocity of recoil of the platform after N shells are fired, is `V_R = (Nmv)/(M-mN)`.

A gun is mounted on a platform fitted with frictionless wheels. The mass of the plarform with the gun, shells and the operator is M. The gun fires shells one after another with a velocity v in the horizontal direction. If mass of each shell is m. show that the velocity of recoil of the platform after N shells are fired, is V_(N) = (Nmv)/((M - mN)) .

A cannon is set on a wooden platform fitted with wheels. Total mass of cannon, cannonball, artillery man and platform is M, and that of a cannonball is m. What will be the velocity of the platform when n number of cannonballs are fired horizontally at velocity v?

A bullet of mass 6 g is fired with a velocity of 500 m cdot s^(-1) from a gun of mass 4 kg. Find the recoil velocity of gun.

A body of mass m moving with velocity V along the X-axis, collides with another mass M moving with velocity v along the Y-axis. The masses coalesce after collision. Find the velocity and the direction of motion of the combined mass.
