Question

When a velocity of a body is increased 5 times what is the change in kenetic energy
​

Answer 1

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. Therefore the velocity is increased by 25 times.

Answer 2

Answer⤵️⤵️

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. Therefore the velocity is increased by 25 times.
