What is the total mechanical energy of the sled

Reference no: EM13537330

A sled and rider with a combined mass of 50 kg are at the top of a hill 20 m above the level of ground below. The sled is given a push providing an initial kinetic energy at the top of the hill of 1050 J.

(a) Choosing a reference level at the bottom of the hill, what is the potential energy of the sled and rider at the top of the hill?

(b) After the push, what is the total mechanical energy of the sled and rider at the top of the hill?
