Question: A 65.0-kg snowboarder works on a half-pine event from top of one side of the semicircle (7.00 m radius) to the other side.
Part A: What is the minimum work that the snowboarder has to do in order to go up 1.50 m above the edge on the other side?
Part B: If the average kinetic friction between the snow and the board is 321 N, how much more work is required from the snowboarder?
