    1.  Explain why a car is accelerating when the it has the cruise control on but is traveling around a     curve on the highway?

    2.  If the current in a river is 3 m/s and the speedometer on the boat reads 10 m/s, how fast does the     boat appear to travel from shore?  How long would it take the boat to travel the 2000 meter trip     upstream?  Give another example that would be similar to this situation.

    3.  David takes off from the stop sign at a tremendous rate of .05 m/s2 and accelerates for 25 seconds.      What is David's amazing final speed?

Revisit the ticker tape activity.  Each group needs:
                        1. one set(constant vel. and one changing vel.) of good ticker tape.
                        2. Explanation and work to show how to calculate the average constant velocity.
                        3. Explanation and work to show how to calculate the acceleration of the object.

            -Discuss the results of the activity.

Discuss acceleration, diagrams to analyze motion, and graphing.

Turn on your computers please and get into examview.

We will be taking the final exam for the class today.  You grade will not have an impact on you class grade. 

The only homework you will have for today is to finish your vocabulary.
