In the two cases shown below, a person is standing on a scale in an elevator. The elevators are identical, and the person weighs 500 N. In both cases the elevator is moving upward, but in Case A it is accelerating upward and in Case B it is accelerating downward. A в y = 3 m/s v = 3 m/s a=2 m/s Ja=2 m/s? Will the scale reading in Case A be greater than, less than, or the same as the scale reading in Case B? Explain with a calculation or in words.
