velocity of a body is increased by 5 times what happens to its kinetic energy?

Formula for kinetic energy is 1/2 m v^2 If velocity of a body is increased by 5 times, then v^2 will increase by 25 times but mass is still of body as it is not changing. So, kinetic energy will increase by 25 times.

KE = 1/2 mv2

If the velocity is increased by 5 times then (5v)2 = 25v2

Therefore the velocity is increased by 25 times.
