Suppose a 55 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1600 kg·m2. The turntable is at rest initially, but when the person begins running at a speed of 3.3 m/s (with respect to the turntable) around its edge, the turntable begins to rotate in the opposite direction. Calculate the angular velocity of the turntable. (Assume the person is running in the positive direction.)
