Speed and Velocity - Problems I.4.1

Construct an appropriate table and a position versus time graph from the following. Does the car have uniform or non-uniform motion? Explain. Calculate the car's average speed between 2 s and 4 s. Would the car's average speed equal its average velocity? Why or why not? What is the car's instantaneous speed at 3 s? What is the car's displacement between 1 s and 3 s? Determine the slope of this position-time graph and derive its correct units. What does the slope represent? Determine the slope of the straight line segment and derive its correct units. What does the slope represent?
