An ice skater, depicted below, has a moment of inertia when her arms are stretched out ("a") of 1 = 2.0 kg-m. She rotates with an angular velocity of 1.0 revolutions/s in this configuration. When she pulls her arms inward ("b"), she rotates with an angular velocity of 2.5 revolutions/s. What is her moment of inertia when her arms are pulled inward?
