8. (II) (a) What is the angular momentum of a figure skater spinning at 2.8 rev/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 15 cm, and a mass of 48 kg? (b) How much torque is required to slow her to a stop in 5.0 s, assuming she does not move her arms? 9.5 kg-m/s -1.9 m.N *53. (II) A 220-g top spinning at 15 rev/s makes an angle of 25 to the vertical and precesses at a rate of 1.00 rev per 6.5s If its ch is 3.5 em from its tip along its symmetry axis what is the moment of inertia of the top? 8.3x10*kg•m
