Problem
Mother is connected to a stroller of mass m with a string of length l that is initially fully stretched. The coefficient of friction between the floor and mother resp. stroller is f. Mother starts pulling the stroller with constant velocity v that is perpendicular to the initial orientation of the string. Describe the dependence of the trajectory of the stroller on system parameters. Assume both the mother and the stroller have negligible size. We recommend that you numerically simulate this problem.
