A passenger of mass m stands on a platform scale in an elevator cab. We are concerned with the scale readings when the cab is stationary and when it is moving up or down. (a) Find the scale reading, whatever the vertical motion of the cab. (Show all steps of your derivation of any results) and, If m = 80.5 kg, (b) what does the scale read if the cab is stationary or moving upward at a constant velocity 0.80 m/s?, (c) What does the scale read if the cab accelerates upward at 4.50 m/s2 and downward at 5.30 m/s2?, (d) During the downward acceleration in part-(c), what is the magnitude of the net force on the passenger, and what is the magnitude of his acceleration as measured in the frame of the cab? Thus using the newtonâs second law, prove that frame of the cab is non-inertial?, (e) If the elevator cab and its load have a combined mass of 1600 kg, find the tension in the supporting cable when the cab is moving with a upward acceleration given in part-(c).
