Calculate the amount of gravitational potential energy at the top of one hill and at the bottom of one valley. The mass of the coaster is 500 kg. The height from the hill to the valley is 59.6 m. Use 9.81 m/s^2 as the acceleration due to gravity. Record your calculations in joules. (Hint: Gravitational PE = mgh)

Gravitational potential energy at the top of the hill:

GPE = mgh
GPE = 500 kg * 9.81 m/s^2 * 59.6 m
GPE = 291678 J

Gravitational potential energy at the bottom of the valley:
GPE = mgh
GPE = 500 kg * 9.81 m/s^2 * 0
GPE = 0 J
