A 250 g, 40.0-cm-diameter turntable rotates onfrictionless bearings at 61.0 rpm. A 17.0 g block sits at the center of the turntable. A compressed spring shoots the block radically outward along africtionless groove in the surface of the turntable.
What is the turntable's rotation angular velocity when the blockreaches the outer edge? (rpm)
