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...

3) A car rounds a circular curve of radius 80.0 m banked at 15⁰ to the horizontal at 30.0 m/s. What is the coefficient of friction required for the car not to skid? Some hints. first, set the x-axis as horizontal, and the y-axis as vertical (this is different than how we normally handle inclines). Second, there will be 3 forces: the normal force (with x- and y- components), the force of gravity (y-component only), and friction pointing down the...
