Acylinder with rotational inertia i l = 2.0 kg . m2 rotates clockwise about a vertical axis through its center withangular speed ml = 5.0 rad] s. = 5.0 rad/s. a second cylinderwith rotational inertia [2 = 1.0 kg . m2rotates counter clockwise about the same axis with angular speed m2 = 8,0 rad/s , if the cylinders couple so theyhave the same rotational axis what is the angular speed of the combination? what percentage of the original kineticenergy is lost to friction?
