Answer 1

Answer:

Answer 2

Question :-

If action is always equal to the reaction, explain how a horse can pull a cart?

Answer :-

The third law of motion states that action is always equal to the reaction but they act on two different bodies.

In this case the horse exerts a force on the ground with its feet while walking, the ground exerts an equal and opposite force on the feet of the horse, which enables the horse to move forward and the cart is pulled by the horse.
