Answer the following questions using the graph at right, which shows the velocity of a runner over time. The letters A and B represent the areas of the two regions in the diagram. Homework Help ✎
Describe the motion of the runner during the time that is illustrated in the graph.
What is the significance of point p
What does the area A represent in this situation? That is, what does it tell you about the runner? What about area B?
If A = 30 meters and B = −5 meters, what does A + B represent in this situation? Why is B negative?
Include information about the direction that the runner was moving.
How does the runner's motion change when s/he reaches point p?
What does area under a velocity curve represent?
