Alarge wooden turntable in the shape of a flat uniform disk has a radius of 2.00 m and a total mass of 100 kg . the turntable is initially rotating at 4.00 rad/s about a vertical axis through its center. suddenly, a 65.0-kg parachutist makes a soft landing on the turntable at a point near the outer edge.
1. find the angular speed of the turntable after the parachutist lands. (assume that you can treat the parachutist as a particle.)2. compute the kinetic energy of the system before and after the parachutist lands. why are these kinetic energies not equal?
