A person starts with a speed of `sqrt((0.5gr))` at the top of a large frictionless spherical surface, and slides into the water below (see the drawing). Then , the person

A small block slides with velocity v_0=0.5sqrt(gr) on the horizontal frictiohnless surface as shown in the fig. the block leaves the surface at point C. The angle theta in the figure is:
