Today we just did some practice problems. They are homework if you didn't finish in class:
p. 228 #18, 20, 32, 65
You also picked up FRQ2009Bb1. This is also homework, but you will be correcting it yourself and keeping it on Monday/Tuesday. It is the basis for the lab you are doing on Monday/Tuesday, Finding g with Centripetal Force. Note: period is the time something takes to complete one cycle. For something moving in a circle, period is the time it takes to complete one rotation/revolution.
