Two identical discs are moving with the same kinetic energy. One rolls and the other slides. The ratio of their speeds is:

Two identical rings are moving with equal kinetic energy One ring rolls without slipping and other ring is in pure translational motion. The ratio of their respective speeds of centre of mass is

Two bodies of different masses are moving with same kinetic energy. Then, the ratio of their moment is equal to the ratio of their

Two bodies of different masses are moving with same kinetic energy. Then, the ratio of their moment is equal to the ratio of their

Two spheres of same material are moving with kinetic energies in the ratio 108 : 576. If the ratio of their velocities is 2 : 3, the ratio of their radii is
