Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.3 kg m? and for arms and legs in is 0.90 kg - m?. If she starts out spinning at 4.1 rev/s , what is her angular speed (in rev/s) when her arms and one leg open outward?

Part A
Ice skaters often end their performances with spin
turns, where they spin very fast about their center of
mass with their arms folded in and legs together.
Upon ending, their arms extend outward, proclaiming
their finish. Not quite as noticeably, one leg goes out

Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.3 kg m? and for arms and legs in is
0.90 kg m?. If she starts out spinning at 4.1 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.
