Section 4.2 4. Oliver is warming up for a track meet. First he walks 1 m/s for
100 seconds. Then he runs at 3 m/s for 200 seconds. His shoe
comes untied, so he stops for 20 seconds to tie it. Finally he runs
at 4 m/s for 200 seconds.
a. Draw a position vs. time graph of Oliver's motion. (Hint: Use
the table below to calculate Oliver's position during each part
of his warm up.)
b. Draw a speed vs. time graph of Oliver's motion.
c. What is the total distance that Oliver travels?
d. What is Oliver's average speed during his 520-second
warm up?
