A playground toy has four seats, each \(5.0 \mathrm{~kg}\), attached to very light, \(1.5-\mathrm{m}\)-long rods, as seen from above in Figure P7.39. If two children, with masses of \(15 \mathrm{~kg}\) and \(20 \mathrm{~kg}\), sit in seats opposite one another, what is the moment of inertia about the rotation axis?
