Follow Up/HW: Practice 8A #1 and section review
Objective: Line up their car and let it do what it was designed for---completing
large amount of work. To race work cars to a great finishing grade
Activities: Perform the actions necessary to prepare your car for its trial.
Line up the cars and let them go, and then measure the distance they covered.
After all magnitudes are recorded each student must calculate overall work
Materials: Project
