D. If the speed of a body is increased four times, how will its kinetic energy be affected? Show by calculation.

e. By how many times will the kinetic energy of a body increase if its speed is tripled?
Show by calculation.

f. What change should be expected in the velocity of a body to maintain the same
kinetic energy, if its mass is increased sixteen times? How?

Is in less time than B. who has more power
