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)

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...
