The problem:

A graph is constructed representing velocity vs. clock time for the interval between clock times t = 5 seconds and t = 13 seconds. The graph consists of a straight line from the point (5 sec, 16 cm/s) to the point (13 sec, 40 cm/s).

1. What is the clock time at the midpoint of this interval? 9s

2. What is the velocity at the midpoint of this interval? 28cm/s

3. How far do you think the object travels during this interval? 224cm

4. By how much does the clock time change during this interval? 8s

5. By how much does velocity change during this interval? 24cm/s

6. What is the rise of the graph between these points? 24cm/s

7. What is the run of the graph between these points? 8s

8. What is the slope of the graph between these points? 3.125cm/s^2

9. What does the slope of the graph tell you about the motion of the object during this interval? The velocity of the object is increasing, that is, it is accelerating.

10. What is the average rate of change of the object's velocity with respect to clock time during this interval? 3.125cm/s^2
