Astudent on a piano stool rotates freely with an angular speed of 2.85 rev/s . the student holds a 1.50 kg mass in each outstretched arm, 0.789 m from the axis of rotation. the combined moment of inertia of the student and the stool, ignoring the two masses, is 5.53 kg⋅m2 , a value that remains constant. as the student pulls his arms inward, his angular speed increases to 3.60 rev/s . how far are the masses from the axis of rotation at this time, considering the masses to be points
