Assume that the tow bar pulls each skier a distance of 200m along the snow and in the process raises them by a vertical distance of 50m. The tow rope pulls each skier along at a constant velocity. A child skier has a mass of 30kg and an adult skier has a mass of 100kg. Assume for now that ski conditions are perfect and the snow is frictionless. How much work does the tow rope do on a child skier...

In the figure, a T-bar ski tow pulls a skier up a hill inclined at 10.º above horizontal. The skier starts from rest and is pulled by a cable that exerts a tension T at an angle of 30.º above the surface of the hill. The mass of the skier is 60. ke and the effective coefficient of kinetic friction between the skis and the snow is 0.10. 30 (a) Draw the free-body diagram for the skier. (4 pts) 400...
Diego pulls a 4.5 kg sled across level snow with a force, F, of 230 N on a rope that is 35.0° above the horizontal
Diego pulls a 4.5 kg sled across level snow with a force, F, of 230 N on a rope that is 35.0° above the horizontal. If the sled moves a distance of 65.5 m, how much work does Diego do? what formula do i use?

1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...
