If ' and '' are given, determine the magnitudes of the roller’s velocity and acceleration at the instant = 1 . Neglect the size of the roller. Also determine the velocity components v Ax and v Ay of the roller at this instant. The rod to which the roller is attached remains vertical and can slide up or down along the guides
