A 45 kg fiure skater is spinning on the toes of her skates at 1.0 rev/s. her arm outstretched as far as they will go. in this orientation, the skater can be modeled as a cylindrical torso(40kg, .2m average diameter,1.6m tall) plus two rod-like arms(2.5kg, .66m long) attached to the outside of the torso. the skater then raises her arms straight above her head, where she appears to be 56 kg, 20 cm-diameter, 200 cm tall cylinder. what is her new rotation frequency in revolutions per second?
