Question

How can a horse pull a cart of action and reaction is equal?​

Answer 1

Answer:

According to Newton's third law ,every action has equal and opposite reaction.

The horse pushes backward on the ground, so the ground pushes forward with an equal force.

Its totally the ground which allows a horse to pull Cart.

By Newton's third law the cart must then exert an equal and opposite force on the horse

Answer 2

Answer:

Two answers are given choose the answer which you like the most

Explanation :

*let the weight of the cart be x

and the force exerted by the horse in a stationary position be y

we know that action and reaction force are equal

∴ x = y

*but in this situation the horse pulling the cart

*so the cart is in a motion and there is an acceleration

*but F =ma

and W = ma [ ∵ weight is a measure of force ]

* the acceleration of the cart will be equal to the acceleration of horse

also W = ma

 m = W/a

Now

 Force exerted by the horse = Force exerted by the Cart

 ma = ma

 ma = W

 [∵ m = W/a]

 W = W

∴ a horse pull a cart of action and reaction is equal

                        or

According to Newton's third law ,every action has equal and opposite reaction. The horse pushes backward on the ground, so the ground pushes forward with an equal force. Its totally the ground which allows a horse to pull Cart. By Newton's third law the cart must then exert an equal and opposite force on the horse.
