Chapter 13, Problem 13.186(choose chapter or problem)
A 70-g ball B dropped from a height \(h_{0} = 1.5 \ m\) reaches a height \(h_{2} = 0.25 \ m\) after bouncing twice from identical 210-g plates. Plate A rests directly on hard ground, while plate C rests on a foam-rubber mat. Determine (a) the coefficient of restitution between the ball and the plates, (b) the height \(h_{1}\) of the ball’s first bounce.

ANSWER:
Problem 13.186
A 70 g ball B dropped from a height reaches a height
after bouncing twice from identical 210 g plates. Plate A rests directly on the hard ground, while plate C rests on a foam rubber mat. Determine (a). The coefficient of restitution between the ball and the plates, (b) the height
of the ball’s first bounce.
