A figure skater is spinning at a rate of 0.75 revolutions per second with her arms close to her chest. She then extends her arms outwards and her new rotational frequency is 0.50 revolutions per second. What is ratio of her new moment of inertia to her original moment of inertia?
A figure skater is spinning at a rate of 0.80 revolutions per second with her arms close to her chest
A figure skater is spinning at a rate of 0.80 revolutions per second with her arms close to her chest. She then extends her arms outwards and her new rotational frequency is 0.40 revolutions per second. What is ratio of her new moment of inertia to her original moment of inertia?
A skater rotates at 3 revolutions per second with her arms stretched.
A skater rotates at 3 revolutions per second with her arms stretched. What must she do to decrease her moment of inertia? Need more information stretch both arms and foot out. stretch her foot out.pull her arms in
A figure skater is spinning slowly with arms outstretched. She brings her arms in close to her body and her moment of inertia decreases by 12
A figure skater is spinning slowly with arms outstretched. She brings her arms in close to her body and her moment of inertia decreases by 12. By what factor does her rotational Kinetic energy change?

A figure skater spins with her arms outstretches at a rate of 10 rev/s. When she pulls her arms closer to her body, her moment of inertial about the spin axis decreased by 10%, what is the skaters new rotational rate in rev/sec?
An ice skater is spinning at 2.5 revolutions per second and has a moment of inertia...
An ice skater is spinning at 2.5 revolutions per second and has a moment of inertia of 0.85 kg m2. Estimate her rotational angular momentum, assuming for simplicity that she can be approximated as a rigid, axially-symmetric body.
An ice skater has a moment of inertia of 5.0 kg-m^2 when her arms are outstretched....
An ice skater has a moment of inertia of 5.0 kg-m2 when her arms are outstretched. At this time she is spinning at 3.0 revolutions per second (rps). If she pulls in her arms and decreases her moment of inertia to 2.0 kg-m2, how fast will she be spinning? A) 7.5 rps B) 8.4 rps C) 2.0 rps D) 10 rps E) 3.3 rps
A figure skater during her finale can increase her rotation rate from an initial rate of...
A figure skater during her finale can increase her rotation rate from an initial rate of 1.14 revolutions every 1.98s to a final rate of 2.94 revolutions per second. If her initial moment of inertia was 4.52kg*m2, what is her final moment of inertia? I need the correct answer in order to give full rating.
A figure-skater finishes her routine with a dramatic spin. Initially, she spins at a rate of 1.3 rev/sec
A figure-skater finishes her routine with a dramatic spin. Initially, she spins at a rate of 1.3 rev/sec. During this time, the figure skater has her arms stretched out. In each hand, she holds a mass of 2.3 kg at a distance of 0.65m from the center of her body. She then pulls her arms in so that the masses are tucked into the middle of her chest. The moment of inertia of her head-torso-legs remains fixed at 24 kg-m2....

A skater has a moment of inertia of 100 kg . m^2 when his arms are outstretched and a moment of inertia of 75 kg . m^2 when his arms are tucked in dose to his chest. If he starts to spin at an angular speed of 2.0 rps (revolutions per second) with his arms outstretched, what will his angular speed be when they are tucked in?
