A 220 45.0-cm-diameter turntable rotates on frictionless, Ask an Expert

Academics

Q. A 220, 45.0-cm-diameter turntable rotates on frictionless bearings at 55. A 21.0 block sits at the center of the turntable. A compressed spring shoots block radically outward along a frictionless groove in the surface of the turntable.

What is the turntable's rotation angular velocity while the block reaches the outer edge?
