A horse continues to apply a force to move a cart with a constant speed so as to overcome the force of friction between the cart and the ground. Once the cart starts moving, the force of friction comes into action. It starts working on the wheels of the cart in a direction opposite to the direction of motion of the cart. So, the horse has to apply a continuous force in the forward direction to maintain constant speed.
