A snowboarder and her board (combined mass 40.0kg) are moving at 9.30m/s at the bottom of a curved ditch. a. (10 pts) If friction can be ignored, what is the maximum vertical distance that she can travel up the sides of the ditch? b. (10 pts) The snowboarder finds that, due to friction, the maximum vertical distance she can travel up the sides of the ramp is 3.50m. How much work did the force of friction do on her?
