Thomas is designing a new ramp for launching ping-pong balls. The ping-pong ball rolls without slipping down a ramp of incline 70 and then up a ramp at 45, which launches it into the air. The ping-pong ball needs to be launched a horizontal distance of 1 meter across a flat table. How high above the surface of the table should the ball be placed in order to launch this far? The ping-pong balls are hollow spheres with mass m = 2.7 g and radius R = 20 mm. 1 m 70 450
