9. A 45 kg figure skater is spinning on the toes of her skates at 1.0 rev/s. Her arms are outstretched as far as they will go. IN this orientation

the skater can be modeled as a cylindrical torso (40 kg,20 cm average diameter, 160 cm tall) plus two rod-like arms (2.5 kg each, 66 cm long) attached outside of the torso. The skater then puts her arms down at her side where she appears to be a 45 kg, 28 cm diameter, 160 cm tall cylinder. What is her new angular velocity, in rev/s? [5 pt]
