A cylinder with rotational inertia I₁ = 2.4 kg · m² rotates clockwise about a vertical axis through its center with angular speed ω₁ = 5.8 rad/s. A second cylinder with rotational inertia I₂ = 1.3 kg · m² rotates counterclockwise about the same axis with angular speed ω₂ = 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)?
