A man pulls a sled loaded with fish. The total mass of the sled and the fishes is 50.0kg and the man exerts a force of magnitude 1.20 x 102 N on the sled by pulling on the rope. a. If the coefficient of kinetic friction between the loaded sled and snow is 0.200, how much work does he do on the sled if he exerts a force of 120N at an angle Ɵ = 30.0° and he pulls the sled at the same distance? b. At position x=12.4m, the man let go on the rope and the sled brings to rest at x=18.2 m. If the ice and the sled has a friction force of 45N in between them, how much work does the friction do on the sled?
