Find the total mechanical energy of the sled and rider

Reference no: EM13670041

A sled and rider with a combined mass of 55 kilogram are at the top of a hill a height of 35 meter above the level ground below. The sled is given a push providing an initial kinetic energy at the top of the hill of 1800 Joule.

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

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

(c) If friction can be ignored, determine what will be the kinetic energy of the sled and rider be at the bottom of the hill?
