A 45 kg figure skater is spinning on the toes of her skates at 1.2 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, 69 cm long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to be a 45 kg , 20- cm -diameter, 200- cm -tall cylinder.

What is her new rotation frequency, in revolutions per second?
