A solid sphere of mass 5 kg and and radius 1 m after rotating with angular speed `omega_(0)=40 rad//s` is placed between two smooth walls on a rough ground. Distance between the walls is slightely greater than the diameter of the sphere. Coffiecient of friction between the sphere and the ground is `mu=0.1`. sphere will stop rtotating after time t = ...........s .
