A horse pulls a cart along a horizontal road with a force of 180N at an angle of 31 degrees with respect to the horizontal and moves along at a speed of 8.0 km/hr. If we can assume that the horse and the cart represent a closed system, then if the horse comes down to 10% of its original speed, the velocity of the cart will be the horse's decrease in velocity multiplied by the ratio of the horse's mass to the cart's mass. If the horse tries to pull the cart, the horse must exert a force on the cart. Law force pair - "horse pushes ground" and "ground pushes horse". If M h and M c be the masses of the horse and the cart and the magnitude of the force exerted by the cart on the horse is F cart, then the acceleration of the horse and the cart is (F id – F cart)/M h = F cart /M c. The external force just cancels fully or partially the internal backward force and does not supply any impulse to the horse-cart system. Does it violate Newtons second law of motion?
