A block of metal is placed on a top of a half-sphere made of ice. The block slides on the half-shpere down to a height (h) above the ground, then it loses contact with the ice surface and falls to the floor. The half-shere has a radius of (R=1m); 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.
