1. A ping pong ball (ball #1, mass of 2g) is held just above a tennis ball (ball #2, mass of 57g) with their centers vertically aligned. When the balls are released, they fall through a vertical distance of 1.27 meters. a) Prove that each ball is traveling at 5.00 m/s just before it hits the ground. The tennis ball (#2) hits the ground and bounces elastically off of it before the ping pong ball (#1) actually hits #2. Since...

A pendulum, consisting of a ball of mass m on a light
string of length 1.00 m, is swung back to a 45° angle and released
from rest. The ball swings down and, at its lowest point, collides
with a block of mass 2mthat is on a frictionless
horizontal surface.
Note that you will most likely get different numbers for the
different parts below. As usual, a good way to handle that is to
solve the problem using variables, and...

A tennis ball of mass 57.0 g is held just above a basketball of mass 577 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.15 m, as shown in the figure below. (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...
