Problem
A 70kg student stands on a calibrated scale inside an elevator that is moving straight upward. For the first 2.0s after the doors close, the elevator accelerates upward at 1.5m/s2.
(a) Calculate the magnitude of the normal force exerted by the scale on the student while the elevator is accelerating. Express your answer in newtons.
(b) Determine what the scale would read (in newtons) after the 2.0s interval once the elevator continues upward at constant speed.
