As shown in the figure (Figure 1), a superball with mass m equal 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 sub [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 J sub [y], the y component of the impulse imparted to the ball during the collision.
D.) Find the y component of the time-averaged force F sub [avg, y], in newtons, that the table exerts on the ball.
E.) Find K (after)−K (before), the change in the kinetic energy of the ball during the collision, in joules.
