Question

In heavy rush-hour traffic you drive in a straight line at 12 m/s for 1.5 minutes, then you have to stop for 3.5 minutes, and finally you drive at 15 m/s for another 2.5 minutesPlot a position-versus-time graph for this motion. Your plot should extend from t=0 to t=7.5 minutes.
Assume x=0 and t=0 at the start of your motion.

Part B
Use your plot from part A to calculate the average velocity between t=0 to t=7.5 minutes.

Answer 1

50 m/s

Answer 2

7.4 m/s
