5. A car is 2.0 km west of a traffic light at t= 0 and 5.0 km east of a traffic light at t=6 min. Assume the origin of the

coordinate system is the light and the positive x direction is eastward. (3 points) а.What are the car's position vectors at these two times? b. What is the car's displacement between 0 min and 6 min? What is the car's average velocity between the two points? Record your answer in terms of kilometres per hour.
