If I have a ball/sphere is released from rest, rolls (without slipping) down a ramp, then drops from the table the ramp is on, how many revolutions does the ball make during the fall? The diameter of the ball, height of the ramp, and height of the table are known. And I calculated the horizontal distance the ball travels before landing correctly. I think I calculated the w, v, and centripetal acceleration correctly. But I am not sure how to solve for the number of revolutions the ball makes before falling on the ground. This problem is probably relatively simple, but I might be having issues with it from looking at it for so long and confusing myself. Any help would be appreciated, thanks!
