Question

A sled and rider with a combined weight of 59 kg are at rest on the top of a hill 24 m high.
(a) What is their total energy at the top of the hill?
(b) Assuming there is no friction, what would the total energy be on sliding halfway down the hill?

a. PE max = Mg*h = 59*9.8*24 = 13,877 J.

b. KE + PE = PE max = 13,877 J.
