From a gun of mass M, a bullet of mass m is fired with a velocity v.
If recoil of the gun stops after t seconds, show that `F = (mv)/(t)`.

From a gun of mass 10 kg , a bullet of mass 50 g is fired. Find the recoil velocity of the gun if the velocity of the bullet is 400 m cdot s^(-1) .

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 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 body of mass 10 kg is moving with a velocity of 100 m/s. find the force needed to stop it in 5 seconds.

Calculate the kinetic energy of a bullet of mass 50 g moving with a velocity of 200 m*s^(-1) .

A mass 2m is at rest and another mass m is moving with a velocity. An elastic collision takes place between them. Show that the mass m loses 8/9 part of its initial kinetic energy in this collision.
