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?

Compare and contrast 'displacement' with 'total distance.'
