A large wooden turntable in the shape of a flat uniform disk has a radius of 2.00 and a total mass of 110 . The turntable is initially rotating at 4.00 about a vertical axis through its center. Suddenly, a 80.0- parachutist makes a soft landing on the turntable at a point near the outer edge

Find the angular speed of the turntable after the parachutist lands. (Assume that you can treat the parachutist as a particle.)

Compute the kinetic energy of the system before the parachutist lands.

Compute the kinetic energy of the system after the parachutist lands.

Why are these kinetic energies not equal?

    A roundabout is a type of playground equipment involving a large flat metal disk that is able to spin about its center axis. A roundabout of mass 120kg has a radius of 1.0m is initially at rest. A child of mass 43kg is running toward the edge of the roundabout (meaning, running on a path tangent to the edge) at 2.7 m/s and jumps on. Once she jumps on the roundabout, they move together as a single object. Assume the...
