A student on a piano stool rotates freely with an angular speed of 2.97 rev/s. The student holds a 1.32-kg mass in each outstretched arm, 0.797 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 5.35 kgm2, a value that remains constant. As the student pulls his arms inward, his angular speed increases to 3.46 rev/s. How far are the masses from the axis of rotation at this time, considering the masses to be points
