```										Dear Nitin,
Momentum = mass * velocity = force * time Kinetic Energy = 1/2 * mass * velocity squared Since the mass of your object is not likely changing, it is the velocity which is changing. Therefore, your new velocity is 1.2 times your initial velocity. In the kinetic energy equation, velocity is squared. 1.2 squared = 1.44, and since nothing else is changing, your kinetic energy is now 1.44 times initial. This is an increase of 28.8%.Is The Answer Clear?
