HW due 9/23

This next week, we'll delve more into all of these topics.
1) Significant figures: go to the signficant figure 'self -check' link OR sig figs 2.   Quiz yourself until you feel comfortable determining the number of significant digits in a number. If you haven't learned about sig figs in another class, it might be best to save this assignment until after 9/19.
2) Race Car Problem- we'll talk about position, velocity and acceleration on Monday, 9/19.  Afterwards, you should feel much better prepared for this assignment.
3) Position vs. time graphs: this is an in class assignment- we collected data on 9/15.  We'll analyze it in lab groups at the beginning of next week.
