Consider a horse attached to the cart which is initially at rest. If the horse starts walking forward, the cart also accelerates in the forward direction. If the horse pulls the cart with force F_h in forward direction, then according to Newton's third law, the cart also pulls the horse by equivalent opposite force F_c = F_h in backward direction. Then total force on cart+horse' is zero. Why is it then the 'cart+horse'accelerates and moves forward?
