. A car is travelling at 20 m/s when it pulls out to pass a truck that is travelling at only 18 m/s. The car
accelerates at 2.0 m/s for 4.0 s and then maintains this new velocity. (Assume 2 significant digits.)
[12 Marks)
(a) What distance does the car travel during the period of acceleration?
(b) What is the car's speed at the end of the period of acceleration?
(c) If the car was originally 8.0 m behind the truck when it pulled out to pass, how far in front of the
truck is the car 10.0 s later?
(d) On the same set of axes, sketch what the position-time graph would look like for both the car and
the truck.
