Kristi Yamaguchi a former figure skater who is the 1992 Olympic Champian, a two-time World Champian and 1992 US Champion. In her 1992 Long Program, she made a sharp turn with a radius of 22.6 m and with a speed of 16.1 m/s. Use Newton's second law to determine the acceleration and the angle of lean of Kristi 55.0-kg body.


Please explain and show work if possible.

The outstretched hands and arms of a figure skater preparing for a spin can be considered...
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. 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 kg. When outstretched, they span 1.8 m; when wrapped, they form a cylinder of radius...

Brady is a figure skater. He finds a few of the jumps he does to be difficult, but the rest are easy for him. He must include four jumps in his routine. He always makes the first jump a difficult one. After a difficult jump, there is a 0.4 probability that he'll do another difficult jump, and otherwise he'll do an easy one. After an easy jump, there is a 0.2 probability that he'll do another easy one, and otherwise...

Conservation of Angular Momentum A female figure skater is spinning on ice. Assume that that the surface is basically frictionless. The skater is wearing weighted bracelets as part of the costume for the performance. These weighted bracelets weight .75 kg each. The skater has a spinning routine in the middle of the performance and initially starts spinning with arms stretched wide such that the weighted bracelets are 1 m from the axis of rotation. She has an initial angular velocity...

[15 pts] A figure skater is spinning in place with her arms outstretched at an angular speed of 18.0 rad/s. She then raises her arms straight up to increase her angular speed. Her body has a mass of 58.0 kg and can be treated as a solid cylinder with a diameter of 36.0 cm, while each arm has a mass of 3.5 kg and can be treated as a thin rod of length 0.425 m when outstretched, and a hollow...

A 45 kg figure skater is spinning on the toes of her skates at 1.0 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, 69 cm long) attached to the outside of the torso. The skater then raises her arms straight above her head, where she appears to...
