Question
At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.20m/s^2. At the same instant a truck, traveling with a constant speed of 20.0m/s, overtakes and passes the car.
Answer these questions:
1) How far beyond its starting point does the car overtake the truck?
2) How fast is the car traveling when it overtakes the truck?
3) Sketch an x-t graph of the motion of both vehicles. Take x=0 at the intersection.
4) Sketch a v-t graph of the motion of both vehicles.
