Noah is designing a new ramp for launching ping-pong balls. The ping-pong ball rolls without slipping down a ramp of incline 70 degrees and then up a ramp at 45 degrees which launches it into the air. The ping-pong balls are hollow spheres with mass m=2.7g and radius R=20mm. a) If the ball is placed at a height of h=0.8m above the table what will be the speed of the ping-pong ball when it leaves the ramp?

b) The ping-pong ball needs to be launched a horizontal distance of at least 1 meter across a flat table. Is this starting height sufficient to launch that ball that far?
