An ice skater has a moment of inertia of 2.5 kg. m2 when her arms are extended and a moment of inertia of 1.2 kg. m2 when her arms are pulled in close to her body. If she goes into a spin with her arms extended and has an initial angular velocity of 2.3 rad/s, what is her angular velocity when she pulls her arms in close to her body? Answer in units of rad/
Answers: 2
