Part A What is the angular speed of the turntable when the child is a distance of 2.10 from the center? (Assume that you can treat the child as a particle.) ANSWER: 0.896 rad/s Problem 10.96 A runner of mass 56.0 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 3.10 . The turntable is rotating in the opposite direction with an angular velocity of magnitude 0.210 relative to the earth. The radius of the turntable is 3.10 , and its moment of inertia about the axis of rotation is 81.0 . Part A 2 of 2 Find the final angular velocity of the system if the runner comes to rest relative to the turntable. (You can treat the runner as a particle.)
