I set up a big homework centered on a rotating system. It is Homework 14, available now in Webcourses.
I like it because it also reviews some of the basics of chapters 6 and 7, but in a rotational context. There are several calculations, so each attempt will generate new numbers to calculate with. Read carefully.
Because it is a super review with some nitty gritty calculations, I have set it to give you unlimited attempts. This will let you totally hone your calculation skills in preparation for Exam 2. Nice.
