If a horse pulls on a wagon at rest, the wagon pulls back equally on the horse. Can the wagon be set into motion?

• Yes, because there is a net force acting on the wagon.

• Yes, because there is a time delay between action and reaction.

• No, because the forces cancel each other.

• Yes, because the horse's pull on the wagon is larger than the wagon's pull on the horse.
