A 45 kg figure skater is spinning on the toes of her skates at0.50 rev/s . Her arms are outstretched as far as they will go. Inthis orientation, the skater can be modeled as a cylindrical torso(40 kg , 20 cm average diameter, 160 cm tall) plus two rod-likearms (2.5 kg each, 62 cm long) attached to the outside of thetorso. The skater then raises her arms straight above her head,where she appears to be a 45 kg, 20-cm-diameter, 200-cm-tallcylinder. Part A What is her new rotation frequency, in revolutionsper second? Express your answer to two significant figures andinclude the appropriate units.
