An ice skater is preparing for a jump with turns and has his arms extended. His moment of inertia is 2.1 kg · m2 while his arms are extended, and he is spinning at 0.6 rev/s. If he launches himself into the air at 8.9 m/s at an angle of 45° with respect to the ice, how many revolutions can he execute while airborne if his moment of inertia in the air is 0.7 kg · m2?

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...

An ice skater quickly extends his arms when he turns on himself. Will its kinetic energy be conserved? Will your mechanical energy be conserved? Will its angular momentum be conserved? (Disregard the friction in the time interval that two it takes to extend the arms.) If any of these magnitudes is not preserved tell whether it increases or decreases.
