A horse is pulling a wagon up a hill at an increasing speed. Ignoring all masses except those of the horse and the wagon, which is the case (and why?):
a) the horse pulls on the wagon harder than the wagon pulls on the horse.
b) the horse pulls on the wagon less than the wagon pulls on the horse.
c) the horse pulls on the wagon just as hard as the wagon pulls on the horse?

the answer is c the horse pull,s hard to go up. but the wagon drags back wanting to go back down.
C is correct, Carole.
Newton’s third laws of motion says: “For every action, there is an equal and opposite reaction.”
Which means the forces on the cart and horse must be the same.
