A 1 kg rubber ball is bounced off a hard floor just prior to its hitting the floor, the ball has a downward speed of 2 m/s. Just after it rebounds the ball has an upward speed of 1 m/s:
a. Is the collision elastic or inelastic?
b. The coefficent restitution for the ball/floor collision can be defined as the ratio of the magnitude of the ball's momentum after the collision to the magnitude of the ball's momentum before the collision. The value of the coefficent of restitution is___
c. The ball experiences an impulse magnitude of____
d. Is this impulse directed upward or downward?
e. The work done by the impulsive force on ball is?
