4. A mover wants to push a box down a hall. The mover applies an ‘action’ force on the box (the push). According to Newton’s 3rd law, there is a ‘reaction’ force applied in the opposite direction. The larger the action force applied by the mover, the larger the reaction force will be. How is it possible, then, for the box to move (be accelerated)?
