A figure skater is spinning at a rate of 1.40 rev/s with her arms outstretched. She then draws her arms in to her chest, reducing her rotational inertia to 68.0% of its original value. What is her new rate of rotation?(adsbygoogle = window.adsbygoogle || []).push({});

I am having trouble starting this problem.

I know that

(I)(alpha) = (I)(omega)(t)

however, the problem doesn't mention time..
