The graph begins at t = 0 s when the elevator door closed on the second floor and ends
at t = 20 s when the door opened on a different floor. Assume that the positive directions
for displacement, velocity, and acceleration are upward. Determine...
a. the maximum speed of the elevator
b. the duration of the brief jerk experienced by the elevator centered on 17.5 s
Sketch the corresponding graphs of...
Determine...
e. the most likely floor on which the elevator stopped
