Between two ski hills, there is a valley. Hill 1 is 735m and the second hill is 625m. From point A to point B, a skier skis. The skier starts at rest at point A and finishes at rest at point B. Between the two points, the total length of the path is 4.11m with an average slope of 40 degrees from the horizontal. a) Sketch the free body diagram and show all the forces on the skier. Indicate the location where the gravitational potential energy is equal to zero on the diagram. b) assuming the system is skier and the earth, and there is friction involved between the ski and the snowy ground ( coefficient of kinetic friction), determine the thermal energy that is lost to the surrounding when the skier is skiing from point A to point B in terms of variables, m, L and theta c) Calculate the value of coefficient of kinetic friction between snow and ski which would make the skier stop at the top of the lower point B
