An ice skater has a moment of inertia of 12 kg-m2 when her arms are outstretched. at this time she is spinning at 2.0 radians/s. if she pulls in her arms and decreases her moment of inertia to 6.0 kg-m2and spins at 4.0 radians/s, how much work does she do to pull her arms in?

answer; equivalent to a one(1) horsepower motor;

conduction, convection, radiation
