A cylinder with rotational inertia I1 = 3.4 kg · m2 rotates clockwise about a vertical axis through its center with angular speed ?1 = 5.4 rad/s.A second cylinder with rotational inertia I2 = 1.1 kg · m2rotates counterclockwise about the same axis with angular speed ?2 = 7.0 rad/s. If the cylinders couple so they have the same rotational axis, what is the angular speed of the combination (in rad/s)? What percentage of the original kinetic energy is lost to friction
