Question

A horse is pulling a heavy cart up a hill. The cart has 400 kg of mass inside it. The horse is pulling the cart with 10 N of force. What is the magnitude of the force on the horse due to the cart?

Answer 1

According to Newton's third law, forces always come in pairs, equal in magnitude but opposite in direction.

If the horse is exerting a 10 N force forward on the cart, the cart is therefore exerting a 10 N force backwards on the horse.
