Ahorizontal platform in the shape of a circular disk rotates on a frictionless bearing about a vertical axle through the center of the disk. the platform has a mass of 117.0 kg, a radius of 2.00 m, and a rotational inertia of 4.68×102 kgm2 about the axis of rotation. a student of mass 50.0 kg walks slowly from the rim of the platform toward the center. if the angular speed of the system is 1.75 rad/s when the student starts at the rim, what is the angular speed when she is 0.650 m from the center? 2.98 rad/s
