A simplified free-body diagram of a person. A central dot represents the person. An arrow labeled F_S points vertically upward from the dot. An arrow labeled F_g points vertically downward from the dot. The downward arrow is visibly longer than the upward arrow. To the side of the diagram, a velocity vector arrow points upward and an acceleration vector arrow points downward.
Free-body diagram of the person and motion vectors for the elevator.
A person of mass \(m\) stands on a platform scale in an elevator that is moving upward. As the elevator approaches the top floor, its speed decreases at a constant rate. Which of the following correctly compares the magnitude of the force exerted by the scale on the person, \(F_S\), and the magnitude of the gravitational force exerted by Earth on the person, \(F_g\), and provides a correct justification?
