An ice-skater rotates freely with an angular speed of 3.00 rev/s. The skater holds a 1.00 kg mass in her right hand, outstretched to 0.7 m from the axis of rotation. She holds a 2.00 kg mass in her left hand, outstretched to 0.6 m from the axis of rotation. The moment of inertia of the skater, ignoring the two masses, is 5.00 kgm2, a value that remains constant. As the skater pulls her arms inward to the same distance from the axis of rotation, her angular speed increases to 3.20 rev/s. How far are the masses from the axis or rotation at this time, considering the masses to be points?
