A small body is placed on the top of a smooth sphere of
radius R. Then the sphere is imparted a constant acceleration wo
in the horizontal direction and the body begins sliding down. Find:
(a) the velocity of the body relative to the sphere at the moment of
break-off;
(b) the angle 00 between the vertical and the radius vector drawn
from the centre of the sphere to the break-off point; calculate 00
for w0 = g.
