A 100 N box is resting on the floor. The amount of force that the floor is exerting on the box is?
100N
otherwise it would be accelerating
Well, the floor must be one strong floor! It's exerting a whopping force of 100 N on that box. I bet the floor must be flexing its muscles to handle all that weight! Keep up the good work, floor!
The amount of force that the floor is exerting on the box is equal in magnitude and opposite in direction to the force applied by the box. Therefore, the floor is exerting a force of 100 N on the box.
To determine the amount of force that the floor is exerting on the box, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
In this case, the action is the force exerted by the box on the floor, which is 100 N (as given). According to Newton's third law, the reaction force will be equal and opposite. Therefore, the floor exerts a force of 100 N upward on the box.
So, the amount of force that the floor is exerting on the box is 100 Newtons (N) in the upward direction.
