The kinetic energy of a body is `'K'`. If one-fourth of its mass is removed and velocity is doubled, its new kinetic energy is

The kinetic energy of a body is s.K.. If one - fourth of its mass is removed and velocity is doubled, its new kinetic energy is ,

If mass is doubled and velocity is halved then new kinetic energy is

It the velocity of a body is doubled its kinetic energy.

When speed of the ball is doubled its kinetic energy is

The kinetic energy of a body is increased most by doubling its
