Answer:
(1) - (2)
and
(3) - (4)
Explanation:
Hi!
The Newton's third law states that for every action there's and equal and opposite reaction.
Lets us consider the first force:
<em>(1) the force of the horse pulling on the cart</em>
Therefore, its counterpart, will be a force of the cart pulling on the horse, which is actually:
<em> (2) the force of the cart pulling on the horse</em>
<em />
Analogously, the third force:
<em>(3) the force of the horse pushing on the road</em>
and the fourth force:
<em>(4) the force of the road pushing on the horse </em>
<em />
From a action reaction pair, since the former force acts on the road by the horse, and the latter on the horse by the road
