Consider the velocity vs. time graph of a person in an elevator shown in Figure 2.58. Suppose the elevator is initially at rest. It then accelerates for 3 seconds, maintains that velocity for 15 seconds, then decelerates for 5 seconds until it stops. The acceleration for the entire trip is not constant so we cannot use the equations of motion from Motion Equations for Constant Acceleration in One Dimension for the complete trip. (We could, however, use them in the three individual sections where acceleration is a constant.) Sketch graphs of (a) position vs. time and (b) acceleration vs. time for this trip.

High-speed motion pictures (3500 frames/second) of a
jumping 230 μg flea yielded the data to plot the flea's
acceleration as a function of time as shown in the figure (
Figure 1). (See "The Flying Leap of the Flea," by M.
Rothschild et al. in the November 1973 Scientific
American.) This flea was about 2 mm long and jumped at
a nearly vertical takeoff angle. Use the measurements
shown on the graph to answer the questions.

I need step by step help please.
I am doing a free-fall experiment for Physics and I need to make a position vs. time graph using the average value of release heights that I obtained. Do you know how I would be able to find the values for the time and position graph? The average value of release height is 1.9720736 m.
