Three small spheres A, B, and C, each of mass m, are connected to a small ring D of negligible mass by means of three inextensible,
inelastic cords of length l. The spheres can slide freely on a frictionless horizontal surface and are rotating initially at a speed v0 about ring D, which is at rest. Suddenly the cord CD breaks. After the other two cords have again become taut, determine
(a) the speed of ring D,
(b) the relative speed at which spheres A and B rotate about D,
(c) the fraction of the original energy of spheres A and B that is dissipated when cords AD and BD again became taut.
