In the figure, a T-bar ski tow pulls a skier for 2.0 minutes up a hill inclined at 10 degree above horizontal. The skier starts from rest and is pulled by a cable that exerts a tension T = 431 N at an angle of 30 degree above the surface of the hill. The mass of the skier is 60.0 kg and the acceleration of the skier is 0.400g (w here g = 9.81 m/s^2). There is friction along the slope. Find the work done by each of the forces acting (T, gravity, normal force, and friction) during the 2.0 minute interval
