The drawing shows an extreme skier at bottom of a ski jump. At this point the track is circular with a radius r. Two forces act on the skier, her weight mg and the normal force FN. Which relation describes how the net force acting on her is related to her mass m and speed v and to the radius r? Assume that "up" is the positive direction.
