A figure skater is spinning at a rate of 0.80 revolutions per second with her arms close to her chest
A figure skater is spinning at a rate of 0.80 revolutions per second with her arms close to her chest. She then extends her arms outwards and her new rotational frequency is 0.40 revolutions per second. What is ratio of her new moment of inertia to her original moment of inertia?

An ice skater has a moment of inertia of 5.0 kg-m2 when her arms are outstretched. At this time she is spinning at 3.0 revolutions per second (rps). If she pulls in her arms and decreases her moment of inertia to 2.0 kg-m2, how fast will she be spinning? A) 7.5 rps B) 8.4 rps C) 2.0 rps D) 10 rps E) 3.3 rps

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 cmaverage diameter, 160 cm tall) plus two rod-like arms (2.5 kg each, 64 cm long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to be...
