Skater's Final Angular Velocity
Not what you're looking for?
An ice skater starts spinning at the rate of 1.5rev/s with arms extended. she then pulls her arms close to her body, resulting in a decrease of her rotational inertia to three-quarters of her initial value. What is the skater's final angular velocity?
