This is a question that many have wondered about at some time, I think...
The action goes from the horse to the cart.
The reaction goes from the cart to the horse.
They are applied to different bodies!
And they also go in different directions. So if you would add them (which makes no sense, since they are applied to different bodies), you'd get zero.
So this is a different concept from: all forces on one body should be balanced, if it moves with constant velocity.
The first statement (action=reaction) is always true, the second (forces are zero) is only true with no acceleration. Those two sound similar, but the only similarity is indeed that they are statements about forces :)
The second statement gets true in the form: ifthe forces on a body are balanced, it doesn't accelerate. This is a special case of F=ma

due to the friction . horce exert force in ground in back direction so the reaction take place in foreword direction
