Starting from rest, a car speeds up uniformly to 9.80 m/s in a time of 12.0 s. The car then travels with this speed for 20 seconds before slowing down at a constant rate to a stop in 24.0 seconds. Determine the total distance in meters traveled from start to end. Round your final answer to three significant figures.

How do you answer question 4?
Draw a quantitatively correct graph of velocity vs. time for the following scenario (you will need add numerical labels to the axes) A maintains a constant acceleration with magnitude of 2 m/s^2. At t = 5 s the cart changes direction. What is the displacement of the cart in the first 5 seconds of its motion? How does this differ from total distance traveled (or goes it) over the same time interval?
