# Question: An elevator starts at rest on the ninth floor At

An elevator starts at rest on the ninth floor. At t = 0, a passenger pushes a button to go to another floor. The graph for this problem shows the acceleration ay of the elevator as a function of time. Let the y -axis point upward.

(a) Has the passenger gone to a higher or lower floor?

(b) Sketch a graph of the velocity vy of the elevator versus time.

(c) Sketch a graph of the position y of the elevator versus time.

(a) Has the passenger gone to a higher or lower floor?
