2. Use work-energy theorem to solve this problem. A sled (m = 17.2 kg) starts from rest and slides down a hill that is angled at 40.0 above the horizontal. The coefficient of kinetic friction between the hill and the sled is 0.240. The hill is 2.35 m long. A) How much work is done by each force acting on the sled as it slides down the hill? B) How fast is the sled moving at the bottom of the hill? C) If the sled would slide up the hill with the speed found in part B, would the sled travel less than, greater than, or equal to 2.35 m up the hill? Explain.
