Problem
A 60kg person stands at the edge of a 10kg solid circular turntable of radius 2.0m. Both are initially at rest. A 2.0kg ball moving tangentially at 5.0m/s relative to the ground is caught and held by the person at the rim. Determine the angular speed of the person–turntable–ball system immediately after the catch. Give your answer to two significant figures.
