The Spinning Figure Skater. The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center . When his hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass 8.0 kg. When outstretched, they span 1.8 m; when wrapped, they form a cylinder of radius 25 cm. The moment of inertia about the rotation axis of the remainder of his body is constant and equal to .40 kg*m^2. If his original angular speed is 0.40 rev/s, what is his final angular speed?

Read about and apply the law of consewvation of angular momentum. After all of the help you have been getting here, I was hoping you would start showing some of your own work or thought process.

I or others will be happy to critique your work, once shown.
