Answer
energy possessed by the body due to its motion is called kinetic energy
then the velocity of a body is increased 5 times( 5+ 5+ 5+5+5) , so kinetic energy is 25

Answer:
kinetic energy is a energy possessed by a moving a body-energy possessed due to motion
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.
