A 75.5 kg skier encounters a dip in the snow's surface that has a circular cross section with radius of curvature of $r$ = 10.1 m. If the skier's speed at point A in the figure below is 7.82 m/s, what is the normal force exerted by the snow on the skier at point B? h = 1.79 m. Ignore frictional forces.
