The momentum of a body is numerically equal to its kinetic energy. The velocity of the body is :

The momentum of a body is numerically equal to the kinetic energy of the body. What is the velocity of the body ?

If the momentum of a body is doubled, how will its kinetic energy vary ?

If the momentum of a body is increased n times, its kinetic energy increases

If momentum of a body increase by 25% its kinetic energy will increase by
