What is the angular momentum of a figure skater spinning at 2.0rev/s with arms in close to her body, assuming her to be a uniform cylinder with a height of 1.5 m, a radius of 15cm , and a mass of 48kg ? How much torque(in magnitude) is required to slow her to a stop in 4.4s , assuming she does not move her arms?
