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 as well.
Suppose that the moment of inertia of a skater with arms out and one leg extended is 2.9 kg. m² and for arms and legs in is 0.90 kg-m². If she starts out spinning at 4.6 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.

A device consisting of four heavy balls connected by low-mass rods is free to rotate about an axle. It is initially not spinning. A small
bullet traveling very fast buries itself in one of the balls. In the diagram, m = 0.004 kg, v = 450 m/s, M1 = 1.5 kg, M2 = 0.3 kg,
R1 = 0.8 m, and R2 = 0.3 m. The axle of the device is at the origin (0, 0, 0), and the bullet strikes at location (0.234, 0.765, 0) m.
