Asked by Anabelle
Two students get in an elevator on the ground floor and ride the elevator up to the fifth floor?
Describe what happens to their velocity and acceleration during the trip.
Would their velocity be increasing? There would be upward acceleration at first and then there would be downward acceleration at the end right?

Yes to your answer:
"There would be upward acceleration at first and then there would be downward acceleration at the end". During the middle of the trip, velocity would be constant. It takes about one floor to reach a constant velocity, or decelerate; this varies with the elevator. Some (especially high rise ones) accelerate faster and reach a higher velocity than others
