if i hit a wall with 4N force so wall would also reacts and apply equal force on my hands,according to newton's 3 law. so my question is that,i could apply force on wall because my hands are accelerating and my hand has a mass but in wall's case it has only mass but no acceleration so how is wall applying force on my hands because F=M*A

Expert Answer:

When our hands apply the force on the wall, this force is redistributed amongst the molecules of the wall. The mass of the wall is very large, and hence it will require a large force to produce a considerable acceleration of the wall. The inertia of the wall stops from moving it.
The redistributed force then gets transferred to our hands in accordance with the Newton's third law.
