Refer to the following information for the next six questions.

The following three graphs all represent different views of the same data set with certain "critical pieces missing."

The trick to finding our missing pieces is to work backwards from the "most complete" graph - that is, the graph that does NOT contain any unknown variables. Using the information it contains, and the relationships outlined in the above table, we can solve for the unknowns. 1. By how much did the object's velocity change during the time interval graphed?
 2. Is the object gaining or losing speed?

3. How far did the object travel during the 8 seconds graphed?
 4. Where is the object located at 8 seconds?

5. What is the object's acceleration?
 6. Why is the acceleration negative if the object is gaining speed?
