When a figure skater goes into spin she will begin with her arms extended, and then draws her arms inward. As a result the ice skater spins faster. Describe why this works in terms of angular momentum.

Provide your own example of the conservation of linear momentum in a collision. Use the words elastic, inelastic, and totally inelastic in your explanation.

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...

A skater spins with angular velocity of 12 rad/s with his arms extended. How fast will he spin with his arms byhis sides? Treat the skater’s body as a uniform cylinder of radius R = (your student number) cm; approximate his armsas uniform rods of length L = 40 cm and mass m = 4.5 kg. His total mass excluding arms is M = 80 kg. Student number is 9

A figure skater rotating at 5.93 rad/s with arms extended has a moment of inertia of 2.40 kgm2. If the arms are pulled in so the moment of inertia decreases to 1.81 kgm2, what is the final angular speed? Express your answer in rad/s to two decimal places.

Typed please. An ice skater can change the speed of her rotation by bringing her arms close to her body. Because her angular momentum is approximately conserved, why does she rotate faster? Before she starts spinning, how does she generate rotation in the first place?

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...
