Question
As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is dropped from a height of h; = 1.5 m. It
collides with a table, then bounces up to a height of h = 1.0 m. The duration of the collision (the time during which the
superball is in contact with the table) is tc = 15 ms. In this problem, take the positive y direction to be upward, and use
9 = 9.8 m/s² for the magnitude of the acceleration due to gravity. Neglect air resistance.
