I've been trying this question over and over, getting the same exact answer (0.270 m/s^2), however, it doesn't seem to be the right answer. Can someone please help? A man stands on a scale in an elevator that is accelerating upward. The scale reads 795.5 N. When he picks up a 27.0 kg box, the scale reads 1067.4 N. The man's mass is 79.0 kg. What is the acceleration of the elevator?
