abstract = {For rope constraints in planar motion, unlike the usual polar coordinate method, the superposition method is used to handle them. We point out that the rope has non-zero acceleration at the tangent point with the pulley, and then use the common superposition formula of velocity and acceleration to obtain the acceleration at the end of the rope. Meanwhile, for rigid bodies that generally perform slipless rolling, we also provide an acceleration formula for their tangent points.}
