3. A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g as shown in the figure below. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.20 m. (a) Find the magnitude of the downward velocity with which the basketball reaches the ground. (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is still moving down. Next, the two balls meet in an elastic collision. To what height does the tennis ball rebound? (You can assume the size of both the basketball and the tennis balls are very small compares to the height. That is, you can simply assume the two balls are to tiny points and you don't need to consider their sizes.)

Question

Transcribed Image Text:3. A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g as shown in the figure
below. With their centers vertically aligned, both balls are released from rest at the same time,
to fall through a distance of 1.20 m.
(a) Find the magnitude of the downward velocity with which the basketball reaches the ground.
(b) Assume that an elastic collision with the ground instantaneously reverses the velocity of
the basketball while the tennis ball is still moving down. Next, the two balls meet in an
elastic collision. To what height does the tennis ball rebound? (You can assume the size
of both the basketball and the tennis balls are very small compares to the height. That
is, you can simply assume the two balls are to tiny points and you don't need to consider
their sizes.)
