Question

If action and reaction forces are equal how does a horse pull a cart?

Answer 1

The horse and cart problem is an application of Newton's Third Law, which says: For every action, there is an equal and opposite reaction. If A exerts a force on B, then B will exert anequal and opposite force on A. ... FGH The ground pushes back on the horse. PHC The horse's body pulls on thecart.

Answer 2

hi friends
here's your answer looking for

Let's first understand what the Newton's third law of motion says

⭐ NEWTON'S THIRD LAW OF MOTION :- Newton's third law of motion states that every action has equal and opposite reaction.
we can experience this law in our day to day life.
even don't know how many of the rocket science and many other branch of science work on this law.

now coming back to your question.

if action and reaction forces are equal how does a horse pull a cart?

Basically, when the horse pushes its legs against the floor due to the fiction the equal and opposite reaction can be seen. That results the forward motion off the horse.
And as the horse cart is also combined with the horse. so, as the horse move in forward direction then the cart also move in forward direction.
hence, horse able to pull the cart.

hope you are satisfied with my answer
