An elevator travels at a nearly constant speed from the ground to an observation deck at 160 m. This trip takes 40 s. The trip back down is also at this same constant speed.
a. What is the elevator's speed in meters per second?
b. How long does it take the elevator to reach the restaurants, located 40 m above ground level?
c. Graph the height of the elevator as it moves from ground level to the observation deck.
d. Graph the height of the elevator as it moves from the restaurant level, at 40 m, to the observation deck.
e. Graph the height of the elevator as it moves from the deck to ground level.
