A 45 kg figure skater is spinning on the toes of her skates at1.0 rev/s. Her arms are outstretched as far as they willgo. In this orientation, the skater can be modeled as acylindrical torso (40 kg, 20 cm average diameter, 160 cm tall) plustwo rod-like arms (2.5 kg each, 66 cm long) attached to the outsideof the torso. The skater then raises her arms straight aboveher head, where she appears to be a 45 kg, 20 cm diameter,200-cm-tall cylinder.
What is her new rotation frequency, in revolutions persecond?
