Problem 8.65 A figure skater can increase her spin rotation rate from an initial rate of 1.0 rev every 2.0 s to a final rate of 3.0 rev/s .

If her initial moment of inertia was 4.3 kg⋅m2 , what is her final moment of inertia?

How does she physically accomplish this change?

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 ;...

Diana, a figure skater, is initially spinning at an angular speed 2.50 rev/s, with her arms and legs inward. Assume that she is a uniform cylinder with a height of 1.4 m, a radius of 18 cm, and a mass of 55 kg. Assume no external torques act. a) What is her moment of inertia? b) If she extends her arms outward, what is her new moment of inertia? Assume that her armspan is 1.3 m and her arms are...

A 45 kg figure skater is spinning on the toes of her skates at 0.50 rev/s . Her arms are outstretched as far as they will go. In this orientation, the skater can be modeled as a cylindrical torso (40 kg , 20 cm average diameter, 160 cm tall) plus two rod-like arms (2.5 kg each, 71 cm long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to...

A student sits in a chair that can spin without friction. The student has her hands outstretched and starts rotating at 1.7 rev/s. Her initial rotational inertia about the central axis is 13.00 kg m2. She pulls her hands inward and decreases her rotational inertial to 7.60 kg m2. What is her resulting angular speed after she pulls her hands inward?(rad/s) (in rad/s) What is the ratio of the new kinetic energy of the system to the original kinetic energy?  ...

In this example we see how a system can have constant angular momentum without having a constant angular velocity! A physics professor stands at the center of a turntable, holding his arms extended horizontally, with a 5.0 kg dumbbell in each hand (Figure 1). He is set rotating about a vertical axis, making one revolution in 2.0 s. His moment of inertia (without the dumbbells) is 3.4 kg⋅m2 when his arms are outstretched, and drops to 1.8 kg⋅m2 when his...
