A trapeze artist performs an aerial maneuver. While in a tucked position, she rotated about her center of mass at a rate of wi = 6.27 rad/sec. Her moment of inertia about this acid is Ii= 16.7 kgm^2. A short time later, the aerialist is in a straight position. If the moment of inertia about her center of mass in this position is now If = 32.5 kgm^2, what is her rotational speed wf? (In rad/s)
