(a)What is meant by an isolated system? (b)Out of mass, speed and momentum, which quantity is same for bullet and the gun on firing?

A bullet fired from a gun. As a result the gun recoils the mass of the gun is 100 times the mass of the bullet. The ratio of the kinetic energies of the bullet and the gun will be

Assertion : In case of bullet fired from gun, the ratio of kinetic energy of gun and bullet is equal to ratio of mass of bullet and gun. Reason : In firing, momentum is conserved
