An ice-skater starts to spin while standing upright with her arms fully extended outward. In each of her hands she holds a 1.0-kg dumbbell. Model her body as a 50-kg, 0.20-m–radius cylinder, her arms as uniform 2.0-kg, 0.75-m–long, 0.10-m diameter rods, and the dumbells as point masses. She then draws her arms downward, until they are by her sides, 0.20 m from her axis of rotation. (a) What is her initial moment of inertia? (b) What is her final moment...

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 (Figure 1). 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 1.7 m ; when wrapped, they form a thin-walled...

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. (See the figure below (Figure 1).) When the skater's 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 of 7.5 kgkg . When outstretched, they span 1.8 mm ;...
