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 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.
a. Find Jy, the y component of the impulse imparted to the ball during the collision.
b. Find the y component of the time-averaged force, in Newtons, that the table exerts on the ball.
