1. Henry gets into an elevator on the 50th floor of a
building and it begins moving at t = 2s. The figure
shows the his apparent weight over the next 10 s.
a. Is the elevator’s initial direction up or
down? Explain clearly how you arrived at
this conclusion.
b. What is Henry’s mass?
c. How far has Henry travelled by t = 12 s?
