Q3 (6 pts) The graph on the right shows the velocity of a car as a function of time.
a) (1 pt) At what time does the car reverse
the direction of travel?
b) (1 pt) What is the average acceleration
of the car during the interval from 0 s to
7 s?
c) (2 pts) Sketch the acceleration-versus-
time graph.
d) (2 pts) Sketch the position versus time
graph, assuming the car is at x = 0 at t =
0.
