(10%) Problem 1: Suppose the ski patrol lowers a rescue sled carrying an injured skier, with a combined mass of 90.1 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. W 60 Otheexpertta.com 25% Part (a) How much work, in joules, is done by friction as the sled moves 32.9 m along the hill? Wf = - 1452 Wf = -1452 J Correct! *25% Part (b) How much work, in joules, is done by the rope on the sled over this distance?
