The angular momentum does not change
original rate of rotation times original rotational inertia
=
final rate of rotation times final rotational inertia
A figure skater is spinning at a rate of 1.7 rev/s with her arms outstretched. She then draws her arms in to her chest, reducing her rotational inertia to 62% of its original value. What is her new rate of rotation?
