A 55kg runner runs around the edge of a horizontal turntable mounted on a vertical frictionless axis through its center. The runners velocity relative to the earth has a magnitude 2.8 m/s The turntable is rotating in the opposite direction with an angular velocity of magnitude 0.2 rad/s relative to the earth The radius of the turntable is 3.0 m and the moment of inertial about the axis of rotation is 85 kg/m^2 find the angular velocity of the turntable just after the runner comes to rest relative to the turntable
