A ballerina is performing a solo for The Nutcracker. Halfway through, she begins to spin at 0.5rev/s on her toes with her arms stretched out from her sides, with a moment of inertia of 1.9kgm2. She then pulls her arms to her chest, spinning at 1.3rev/s. What is her moment of inertia when she brings her arms to her chest? (Hint: You may leave the angular velocities in the units given of revolutions/second. Whether you keep them this way or...

A figure skater is spinning on frictionless ice. Treat the figure skater as a sphere with radius R=.4m and mass M=60kg. The skater is holding onto a massless string attached to a weighted ball of m=10kg. The skater is initially spinning at an angular speed w0 of 2pi radians per second (1 rev/s) with a sting radius of r=1m. Moment of inertia for a sphere is I=(2/5)MR^2. 1.) What is the initial total rotational inertia of the skater and ball?...
