Practice Midterms questions.

Enclosed are some practice midterm problems.  An actual midterm will be shorter than this, just 2 or 3 problems; an amount you can reasonably work in 65 minutes. The idea of this is to give you an idea of the equations you will tend to see in the midterm, and to give you some problems to practice on.  Please feel free to engage in discussion with your classmates either person or here in the comments section. You may ask and answer questions about the problem content, approach, how to start, if something you tried is correct, etc. (For really helpful comments, you may get special participation points.)

When you can do a couple of these problems, using just the equations given, in about an hour or less, that would suggest that you are ready for an in class midterm. (Also, please ignore the part d of problem 3 (and the equation for that). We have not covered that yet and it won't be on the midterm.)

On the other hand, please do not ask when I will post solutions.  When I see that, especially just after the problems have appeared, I tend to wonder if you may not actually plan on doing them yourself.

Doing them yourself with just blank paper and the equation sheet is the best way in my opinion.
