Three objects, starting from rest at the same altitude, roll without slipping down an inclined plane. One is a ring of mass \(M\) and radius \(R\); another is a uniform-density disk of mass \(2 M\) and radius \(R\), and the last is a uniform-density sphere of mass \(M\) and radius \(2 R\). In what order do they reach the bottom of the inclined plane?
