As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is
dropped from a height of h₁ = 1.5 m. It collides with a table, then bounces up to
a height of hf = 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 g = 9.8 m/s² for the magnitude of the
acceleration due to gravity. Neglect air resistance.
