Question

The kinetic energy of an object of mass Mand moving with a velocity of 5 M per second is 25 joules. what will be its kinetic energy when its velocity is doubled ?what will be the kinetic energy when its velocity by increased by 3 times?

Answer 1

1.if velocity is doubled k.e =2×25=50.
2. if velocity is tripled it is 3×25=75.
