Problem 8 - Circular Motion and Conservation of Energy
A block of metal is placed on top of a half-sphere made of ice. The block slides on the half-sphere down to a height h above the ground, then it loses contact with the ice surface
and falls to the floor. The half-sphere has a radius R = 2m; we can ignore the friction between the ice and the metal. a} What is the force exerted by the half-sphere on the block at the moment in which the
block loses contact with the ice? b} Calculate h.
