The drawing shows an extreme skier at three locations on a ski run:
(a) a straight section,
(b) a circular section, and
(c) an airborne phase in which the skier is in free-fall. at the right of the drawing are four possible directions for the net force that acts on the skier. what is the direction of the net force at a, b, and c? assume that there is no friction or air resistance at any point along the ski run.
