The cyclist travels to point A, pedaling until he reaches speed v_A. He then coasts freely up the curved surface. Determine the normal force he exerts on the surface when he reaches point B. The total mass of the bike and man is M. Neglect friction, the mass of the wheels, and the size of the bicycle.
