You will estimate how much slower an ice skater would spin, if a can of soda dropped into her hand while she was spinning. You may model her body as a vertical cylinder of radius 20 cm and mass of 50 kg, spinning about a vertical axis. Assume that she's initally spinning 10 times per second, so that initially wi=20 (pi)s-1. Suddenly she is handed the soda can, which is small enough that we can model it as a point-like...

An ice skater spinning with outstretched arms has an angular speed of 5.0rad/s . She tucks in her arms, decreasing her moment of inertia by 29% . What is the resulting angular speed? rad/s By what factor does the skater's kinetic energy change? (Neglect any frictional effects.) where does the extra kinetic energy come from?
