A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the student-stool system is 4.5 kg. m². A second student tosses a 2.0 kg mass with a speed of 3.0 m/s to the student on the stoole, who catches it at a distance of 0.40 m from the axis of rotation. Assume a right angle between the ball trajectory and radius drawn to the catch point.
