Find the component of the momentum

Question: 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= 1.0m. The duration of the collision (the time during which the superball is in contact with the table) is tc = 15 m/s. In this problem, take the positive y direction to be upward, and use g = 9.8 m/s^2 for the magnitude of the acceleration due to gravity. Neglect air resistance.

1. Find the y component of the momentum, p before y, of the ball immediately before the collision.

2. Find the y component of the momentum of the ball immediately after the collision, that is, just as it is leaving the table.

3. Find the y component of the time-averaged force F avg,y, in newtons, that the table exerts on the ball.

4. Find Jy, the y component of the impulse imparted to the ball during the collision.

5. Find K after- K before, the change in the kinetic energy of the ball during the collision, in joules.
