The changing velocity of a car is represented in the velocityversus- time graph shown in Figure P1.62. (a) Describe everything you can about the motion of the car using the graph. (b) What is the displacement of the car between times 0 s and 45 s? What is the path traveled? (c) What is the average speed of the car during all 70 s? What is the average velocity?
