Question

if action is always equal to reaction, explain why a cart pulled by a horse can be moved​

Answer 1

Answer: The horse moves because the force he exerts with his hooves is greater than the force of the wagon pulling him back. ... The horse pulls it forward, and there is a backward force from the ground; friction. If the horses' pull exceeds the friction of the cart, it will accelerate.

Explanation: When an objects grater than its potential mass as a greater gravitational pull the object with the less mass will ALWAYS be pushed!!!

Answer 2

Answer:

$\large\bf\purple{Here\:is\:your\:answer}$

When a horse pulls a cart,the force which is responsible for the movement of cart is "The force of the ground on Horse" :-

While pulling the cart, the horse pushes the ground with its foot, as a reaction, the ground exerts a force on the horse equal and opposite to applied force by Newton's third law making the horse with the cart move in the forward direction.
