High-speed elevators function under two limitations: (1) the maximum magnitude of vertical acceleration that a typical human body can experience without discomfort is about 1.2 , and (2) the typical maximum speed attainable is about 9.3 . You board an elevator on a skyscraper's ground floor and are transported 230 above the ground level in three steps: acceleration of magnitude 1.2 from rest to 9.3 , followed by constant upward velocity of 9.3 , then deceleration of magnitude 1.2 from 9.3 to rest.
Determine the change in the magnitude of the normal force, expressed as a of your normal weight during each stage.
What fraction of the total transport time does the normal force not equal the person's weight?
