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?© BrainMass Inc. brainmass.com March 4, 2021, 6:44 pm ad1c9bdddf
We know that her kinetic energy should be constant
w1=angular speed with arms stretching, ...
