The solid circular disk with mass m = 3 kg and radius R = 0.7 m rolls without slipping on the horizontal surface, collides with the step at A and continues to 'roll' without slipping about point A to climb the step's change of elevation h = 0.5 m. Assume the collision at A is perfectly. inelastic and determine the minimum initial linear velocity necessary to climb the step. Report the result in m/s. R Vo Not to Scale A In h
