A solid sphere is released from the top of a ramp that is at a height
h1 = 1.95 m.
It goes down the ramp, the bottom of which is at a height of
h2 = 1.38 m
above the floor. The edge of the ramp is a short horizontal section from which the ball leaves to land on the floor. The diameter of the ball is 0.14 m.

(a) Through what horizontal distance d does the ball travel before landing?

(b) How many revolutions does the ball make during its fall?
