• Exercise #1: The following is a "Quicktime" movie of the flight of a small piece of potatoe. Estimate the maximum height of the potatoe's path. Make sure you are specific about your assumptions which you make in your estimation. Is your estimation too large or too small? Quicktime movie. (Hint: The exercise requires calculations. You will need to watch the movie carefully, perhaps with at stop watch.)
• Can you improve your estimate, e.g., using more observations of the movie to estimate air resistance?

The following are the "minimum suggested exercises" that you should do. Exactly which of these that you will be required to hand in will be announced in class
