Academics

A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the student-stool system is 5.0 . A second student tosses a 1.5 mass with a speed of 2.8 to the student on the stool, who catches it at a distance of 0.45 from the axis of rotation.

a) Calculate the intial kinetic energy of the system.

b) Calculate the final kinetic energy of the system.
