You are pulling a rope that is attached to a sled that your cousin is riding on. The rope that you are pulling on is at an angle of 30 degrees above the surface of the snow. Your cousin is holding a second rope that is attached to a second sled that is carrying firewood. The rope that your cousin is pulling is parallel to the surface of the snow. The mass of your cousin and her sled is 45 kg. The mass of the firewood and the sled carrying the firewood is 100 kg. The kinetic friction coefficient between the sleds and the snow is 0.1. Both sleds are speeding up at 0.5 m/s 2. 1.Sketch and label all parameters 2.Draw free body diagrams needed to solve the problems. 3. Determine how much force your cousin needs to pull on the rope attached to the sled with the firewood. 4.Determine the force you are exerting on the rope.
