You are standing on a bathroom scale and you measure the weight to be 120 lb. You then take the scale onto an elevator and stand on the scale as the elevator accelerates, during which the reading on the scale decreases to 90 lb. Which of the following statements about the elevator could be true? A. The elevator is moving upward at 2 m/s while accelerating downward at 2.45 m/s^2. B. The elevator is moving downward at 4 m/s while accelerating upward at 2.45 m/s^2/ C. upward at 4 m/s while accelerating upward at 2.45 m/s^2. D. at rest while accelerating downward at 7.35 m/s^2. E. The elevator is at rest while accelerating upward at 7.35 m/s^2.
