(17%) Problem 2: Suppose the ski patrol lowers a rescue sled carrying an injured skier, with a combined mass of 87.6 kg. down a 60.0 slope at constant speed, as shown in the Figure. The coefficient of kinetic friction between the sled and the snow is 0.100. 25% Part (a) How much work, in joules, is done by friction as the sled moves 29.4 m along the hill? W = -1261.84 W = -1262 J Correct! 25% Part (b) How much work, in joules, is done by the rope on the sled over this distance?
