A runner of mass 52.0 kg runs around the edge of a horizontal turntable mounted on a vertical, frictionless axis through its center. The runner's velocity relative to the earth has magnitude 3.30 m/s. The turntable is rotating in the opposite direction with an angular velocity of magnitude 0.220 rad/s relative to the earth. The radius of the turntable is 2.90 m, and its moment of inertia about the axis of rotation is 79.0 kg m 2 .
