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 $\omega_{1}=5,79 \mathrm{rad} / \mathrm{s}$. Her moment of inertia about this axis is $I_{\mathrm{i}}=16.1 \mathrm{~kg} \cdot \mathrm{m}^{2}$. A short time later, the aerialist is in the straight position, as shown in Figure B. If the moment of inertia about her center of mass in this position is now $I_{\mathrm{r}}=33.1 \mathrm{~kg} \cdot \mathrm{m}^{2}$, what is her Figure A Figure B
