A student on a piano stool is rotating freely with an angularspeed of 3.05 rev/s. the student holds a 1.50 kg mass in eachoutstretched arm, 0.759m from the axis of rotation. The combinedmoment of inertia of the student and the stool, ignoring the twomasses is 5.53 kg m^2, a value that remains constant.

A) As the student pulls his arms inward, his angular speedincreases to 3.69 rev/s. How far are the masses from the axis ofrotation?

B) What is the final and inital KE of the system?
