a superball with mass mequal to 50 grams is dropped from a height of hi=1.5m . It collides with a table, then bounces up to a height of hf=1.0m . The duration of the collision (the time during which the superball is in contact with the table) is tc=15ms . In this problem, take the positive y direction to be upward, and use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Neglect air resistance. a) Find the y component of the momentum, p before y, of the ball immediately before the collision. b) Find the y component of the momentum of the ball immediately after the collision, that is, just as it is leaving the table. c) Find Jy, the y component of the impulse imparted to the ball during the collision.
