A 75 kg person is standing on a bathroom scale in an elevator. The scale is calibrated to read in Newtons. The elevator is accelerating upward at 135 m/s2. What is the reading on the scale? What apparent value of g does the man give? The Free Body Diagram Normal on the man, upward Weight mg of the man, downward My Attempt/Logic The only two forces acting on the man are normal force and weight. FN - mg = ma fN = mg + ma, where N is the reading on the scale. FN = (75)(9.8) + (75)(135) FN = 10860 N The solution reads 8.5x102 N? Am I doing something wrong? This problem seems very basic, but I am obviously missing something.
