A ring of mass 3 kg is rolling without slipping with linear velocity 1 m/s on a smooth horizontal surface. A rod of same mass is fitted along its one diameter. Find total kinetic energy of the system (in J).

A rolling body of mass m = 4 k g radius R and radius of gyration k = R / √ 3 is placed as a plank which moves with an acceleration a 0 = 1 m /s^2 . Find the frictional force acting on the body if it rolls without sliding(in N ).
