Question: A ball is attached to a device that can launch the ball in any direction. The launcher is a large vertical disk of diameter 5.0 m and the ball is affixed at the rim of the launcher. The disk starts from rest and has a constant angular acceleration of 2.1 rads/s2 (not m/s2). After 4 revolutions, the ball is launched horizontally at the top of the launcher.
Part A: How far will the ball travel in the horizontal direction?
I need help to find how far will the ball travel in the horizontal direction and you can assume that air resistance is negligible.
