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?

Answer 1

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

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

Answer 2

3550J
