V Problem 11.58 7 of 8 Review Part A A student on a piano stool rotates freely with an angular speed of 3.05 rev / s . The student holds a 1.05 kg mass in each outstretched arm, 0.769 m from the axis of rotation. The As the student pulls his arms inward, his angular speed increases to 3.55 rev/s . How far are the masses from the axis of rotation at this time, considering the combined moment of inertia of the student and the stool, ignoring masses to be points? the two masses, is 5.43 kg . m , a value that remains constant.
