The speed of rolling of a ring of mass m changes from V to 3V . What is the change in its kinetic energy

Show that work done on a body or by the body is equal to the net change in its kinetic energy.

The momentum of a body is doubled. By what percentage does its kinetic energy increase ?

Mass of a moving body is doubled and velocity is halved . What will be the change in momentum ?

According to the work- energy theorem, work done by a force on a body is equal to change in its kinetic energy. Prove the theorem.
