... Q10.17. Reason: (a) If the car is to go twice as fast at the bottom, its kinetic energy, proportional to v2 , will be four times as great. You thus need to give it four times as much gravitational potential energy at the top. Since gravitational potential energy is linearly proportional to the heig ...
