A man measures the acceleration of an elevator using a spring balance. He fastens the scale to the roof, and suspends a mass from it. If the scale reads 98N when the elevator is at rest, and 93N when the elevator is moving, (a) what is the acceleration of the elevator? (b) in which direction is the elevator accelerating?
