Laura sees a horse pulling a buggy. she wonders how it can accelerate if the action of the horse pulling the cart would causes an equal and opposite reaction of the cart pulling on the horse. which explanation best answers her question? a. the net forces exerted on the the horse and cart are the same, but the action force is larger. b. the net forces exerted on the the horse and cart are the same, but they are in the same direction. c. the net forces exerted on the the horse and cart are not the same, so the two forces cancel out. d. the net forces exerted on the the horse and cart are not the same, so they are not balanced forces.
