Suppose the ski patrol lowers a rescue sled carrying an injured skiier, with a combined mass of 92.5 kg, down a 60.0° slope at constant speed. The coefficient of kinetic friction between the sled and the snow is 0.100.  How much work, in joules, is done by the rope on the sled as the sled moves 30.5 m? What is the net work done on the sled, in joules?
