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...
