Question
You've always wondered about the acceleration of
the elevators in the 101-story-tall Empire State
Building. One day, while visiting New York, you take
your bathroom scale into the elevator and stand on
it. The scale reads 150 lb as the door closes. The
reading varies between 130 lb and 170 lb as the
elevator makes its upward journey.
