A ring, a solid sphere and a thin disc of different masses rotate with the same kinetic energy. Equal torques are applied to stop them. Which will make the least number of rotations before coming to rest?

A ring and a disc of different masses are rotating with the same kinetic energy. If a retarding torque (tau) is applied to the ring, the ring stops after completing n rotations. If the same retarding torque is applied to the disc, how many rotations would it complete before coming to rest?

A ring and a disc of different masses are rotating with the same kinetic energy. If we apply a retarding torque r on the ring and the ring stops after making n revolutions, then in how many revolutions will the disc stop under the same retarding torque ?

A ring and a disc of different masses are rotating with the same kinetic energy. If we apply a retarding torque tau on the ring, it stops after making n revolution. After how many revolutions will the disc stop, if the retarding torque on it is also tau ?

A rigid and a disc of different masses are rotating with the same kinetic energy. If we apply a retarding torque tau on the ring, it stops after making n revolution. After how many revolutions will the disc stop, if the retarding torque on it is also tau ?

Kinetic energy of an object is 1J . A force of 1 Mdyn is applied to stop the object. How far does the object go before coming to rest ?
