Terry is standing in an elevator on a scale. At one point in the elevator ride, he measures that his apparent weight is 924 N. His actual weight is 892 N. Which of the following best describes the motion of the elevator?
 
The elevator is accelerating upwards at 1.04 m/s2
 
The elevator is accelerating downwards at 0.35 m/s2
 
The elevator is accelerating upwards at 0.35 m/s2
 
The elevator is accelerating downwards at 1.04 m/s
