Question

A horse pulls the cart. If the action and reaction are equal and opposite then how doer the cart move?​

Answer 1

Answer:

The force the horse exerts on the cart is of equal size and opposite direction to the force the cart exerts on the horse, by Newton's third law. (These two forces are an action-reaction pair.) ... As the horse exerts greater force, both horse and cart move, accelerating from zero to some velocity.
