Answer 1

when the movement of body is increased by 3 times it's kinetic energy will become thrice than the kinetic energy before

Answer 2

Answer:

If momentum increase by 3 times, then KINETIC ENERGY will increase by 9 times. i.e., "v" is increased by 3 times. So, KE will increase by 3²(=9) times. Since Mass is constant.
