Physics

A cylinder with rotational inertia I1 = 2.6 kg · m^2rotates clockwise about a vertical axis through its center withangular speed ω1 = 5.8 rad/s. A second cylinder withrotational inertia I2 = 1.3 kg · m2 rotatescounterclockwise about the same axis with angular speedω2 = 6.6 rad/s. If the cylinders couple so they have thesame rotational axis, what is the angular speed of the combination(in rad/s)?

What percentage of the original kinetic energy is lost tofriction?
