A large wooden turntable in the shape of a flat uniform disk has a radius of 2.00 m and a total mass of 1.30 ×10² kg. The turntable is initially rotating at 3.60 rad/s about a vertical axis through its center. Suddenly, a 70.0 kg parachutist makes a soft landing on the turntable at a point near the outer edge.
