A trapeze artist performs an aerial maneuver. While in a tucked position, as shown in Figure A, she rotates about her center of mass at a rate of 5.79 rad/s. Her rotational inertia about this axis is 18.5 kg·m². A short time later the aerialist is in the straight position, as shown in Figure B. If the rotational inertia about her center of mass in this position is 30.7 kg·m², what is her rotational speed?
