Suppose a 55 kg person stands at theedge of a 5.5 m diametermerry-go-round turntable that is mounted on frictionless bearingsand has a moment of inertia of 1500kgm2. Theturntable is at rest initially, but when the person begins runningat a speed of 3.4 m/s (with respect tothe turntable) around its edge, the turntable begins to rotate inthe opposite direction. Calculate the angular velocity of the turntable. (Assume the person is running in the positivedirection.)
