Question:

Fun with a Super Ball. A Super Ball has a coefficient of restitution α = 0.90. This means that the y components of the ball???s velocity just before and after hitting the floor are related by v_fy= -αv_if. It is dropped from a height of 1.8 m such that it goes under a table of height 70 cm. The ball bounces back and forth between the underside of the table and the ground (Fig. P7.62). How many total times will the ball bounce off the bottom of the table?
