in. An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force of 1.15 × 102 N on the sled by pulling on the rope. (a) How much work does he do on the sled if the rope is horizontal to the ground (0 = 0° in the figure) and he pulls the sled 5.80 m? (b) How much work does he do on the sled if 0 = 30.0° and he pulls the sled the same distance? (Treat the sled as a point particle, so details such as the point of attachment of the rope make no difference.) (c) At a coordinate position of 5.80 m, the Eskimo lets up on the applied force. A friction force of 46.0 N between the ice and the sled brings the sled to rest at a coordinate position of 10.80 m. How much work does friction do on the sled?
