A uniform ring rolls on a horizontal surface without sliding The velocity of the centre is v It encounters a step of height 0 3 R where R is the radius of the ring Calculate the angular velocity of the ring just after the impact Assume that the ring does not return back and there is sufficient friction to avoid slipping Find the minimum value of v so that the ring ascends the step
