Question 13

Item 13 As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is dropped from a height of hi = 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 to = 15 ms . In this problem, take the positive y direction to be upward, and use g =9.8 m/s' for the magnitude of the acceleration due to gravity. Neglect air resistance.
