1) A block of mass 0.5 kg is placed at the highest point of a fixed smooth sphere
of radius 0.5m. The block is gently pushed to one side. Calculate: 0 the
force exerted by the block on the sphere when it makes an angle
vertical. (ii) At what angle does it leave the sphere ? (iii) At what distance
from the point of contact of the sphere does the block hit the ground?
