The oxygen molecule, O2, has a total mass of 5.30×10-26 kg and a rotational inertia of 1.94×10-46kg-m2 about an axis perpendicular to the center of the line joining the atoms. Suppose that such a molecule in a gas has a speed of 1.48×102m/s and that its rotational kinetic energy is two-thirds (2/3) of its translational kinetic energy. Find its angular velocity.
