A 200 g, 40.0-cm-diameter solid cylindrical turntable rotates on frictionless bearings at 60.0 rpm. A 20.0 g block sits at the center of the turntable. The block then slides outward alonga frictionless groove in the surface of the turntable and stops when it reaches the edge.
For this problem, you can assume that the turntable can be treated as a solid disk and the block can be treated as a point mass.
What is the turntable's angular speed when the block reaches the outer edge of the turntable?
