Final answer:
When applying Newton's Third Law of Motion, action and reaction forces are equal and opposite. No final force is needed as the forces balance out, creating equilibrium.
Explanation:
Action and reaction: Newton's Third Law states that for every action, there is an equal and opposite reaction. An example of this is when a person pushes against a wall, the person exerts a force on the wall, and the wall exerts an equal force back on the person, preventing them from moving through the wall.
Final force needed: In situations like this, no final force is needed because the action and reaction forces balance each other out, resulting in a state of equilibrium where the net force is zero.
