A cylinder with rotational inertia I = 3 kg m rotates clockwise about a vertical axis through its center with angular speed w = 5 rad/s. A second cylinder with rotational inertia I2 = 1 kg m rotates counterclockwise about the same axis with angular speed w = 8 rad/s. a. If the cylinders couple so they have the same rotational axis what is the angular velocity of the combination? Specify the direction using the drop down menu. Wf = 5.75 rad/s clockwise b. What percentage of the original kinetic energy is lost to friction? Round your answer to the nearest whole percentage point. % percentage = 5 A cylinder with rotational inertia I = 3 kg m rotates clockwise about a vertical axis through its center with angular speed w = 5 rad/s.
