**Problem Statement:**A cylinder with rotational inertia \( I_1 = 3.4 \, \text{kg} \cdot \text{m}^2 \) rotates clockwise about a vertical axis through its center with angular speed \( \omega_1 = 5.4 \, \text{rad/s} \). A second cylinder with rotational inertia \( I_2 = 1.1 \, \text{kg} \cdot \text{m}^2 \) rotates counterclockwise about the same axis with angular speed \( \omega_2 = 7.0 \, \text{rad/s} \). If the cylinders couple so they have the same rotational axis, what is the angular speed of the combination (in rad/s)?**Answer Box:**\[ \_\_\_\_\_\_ \, \text{rad/s} \]**Additional Question:**What percentage of the original kinetic energy is lost to friction?**Answer Box:**\[ \_\_\_\_\_\_ \% \]
