Question

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

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

Explanation:

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

Answer : According to 3rd Law of Motion action and reaction forces are equal in magnitude and opposite in direction.

Look, If a horse applies force on cart then cart should have applied force to cancel horse's effect

but actually the horse applies force on ground,

And the ground pushes horse forward ( in the same manner you walk).The cart is connected to horse.

Due to this the horse cart system moves forward.
