A 51 kg skater twirls at 0.64 rev/s with her arms extended. She then brings her arms in and twirls at 0.95 rev/s. The skater's mass moment of inertia can be determined by approximating her to be a uniform cylinder with radius 17 cm when her arms are in.
a. Determine the mass moment of inertia of the skater with her arms extended.
b. Determine the percent of change in kinetic energy when the skater brings her arms in.
