Question

loe skaters often end their performances with spin
turns, where they spin very fast about their conter
of mass with their arms folded in and legs together.
Upon ending, their arms extend outward,
proclaiming their finish. Not quite as noticeably, one
log goes out as well.
Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.1 kg m² and for arms and
legs in is 0.90 kg-m². If she starts out spinning at 5.4 rev/s, what is her angular speed (in rev/s) when her arms
and one leg open outward?
Express your answer in revolutions per second.
