3. A large wooden turntable in the shape of a flat uniform disk has a radius of 2.0 m and a total mass of 120 kg. The turntable is initially rotating at 3.0 rad/s about a vertical axis through its center. Suddenly, a 70 kg parachutist makes a soft landing on the turntable at a point near the outer edge. a) Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle) b) Compute the kinetic energy of the system before and after the parachutist lands. Is the kinetic energy conserved?

A disk with moment of inertia I1 rotates about a frictionless, vertical axle with angular speed i.
