Question

A 7.00kg bowling ball moves at 3.00m/s. How fast must a 2.45g ping pong ball move so that the two balls have the same kenitic energy

Answer 1

Answer #1

let the ping pong moves with velocity V

0.5*7*3^2 = 0.5*0.00245 * V^2

So V = 160.35 m/s

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...
