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​
