a mover is pushing on a very large box with a force of 850N but he cant get it to move. what force is the box exerting on the mover?

To find the force that the box is exerting on the mover, we can use Newton's third law of motion, which states that every action has an equal and opposite reaction. In this case, the mover is pushing on the box with a force of 850N, so the box exerts an equal force in the opposite direction on the mover.

Therefore, the force exerted by the box on the mover is also 850N in the opposite direction.
