1. The problem statement, all variables and given/known data A figure skater is spinning at a rate of 2 rev/s with her arms outstretched. She then draws her arms in to her chest, reducing her rotational inertia to 61% of its original value. What is her new rate of rotation? 2. Relevant equations ? 3. The attempt at a solution w/2 = 1/sqrt(0.61) w = 2.56 rev/s This isn't correct according to the website, can someobody help me with a better equation and how to solve this one? Thanks!
