A solid sphere 0.16 m in diameter is released from rest, rolls down a ramp, and drops through a vertical height of h1 = 0.57 m. The ball leaves the bottom of the ramp, which is h2 = 1.08 m above the floor, moving horizontally.

(a) What distanced does the ball move in the horizontal direction before landing? m

(b) How many revolutions do it completely during its fall (i.e., after it rolls off and before it lands)? rev
