Question
A couple of figure skaters are executing a move called the "death spiral" as shown in the
image below. The male skater on the left is swinging his partner around him on the ice and
we can assume that he is rotating without translating. The coefficient of friction between the
female's skates and the ice is 0.02. The male skater is applying a constant moment of 8 lb-ft
about the axis of rotation to keep the spin going. If the couple is initially spinning at 5 rad/s,
calculate their final angular velocity after 6 seconds. Simplify this problem and treat the
female as a 140 lb particle that is spinning 6' from the axis of rotation only in the horizontal
plane. For full credit, draw an FBD and clearly define your system using polar coordinates.
