A horizontal 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 radius of 1.03 m and a rotational inertia of 444 kg-m? about the axis of rotation. A 65.7 kg student walks slowly from the rim of the platform toward the center. If the angular speed of the system is 2.31 rad/s when the student starts at the rim, what is the angular speed when she is 0.425 m from the center? Number i Units rad/s
