Here you are. It is unlikely that there will detailed solutions before Thursday, but I will try.
Remember, the exam has 7 problems and you must do 5 of them. I will provide a formula sheet with all the necessary equations & constants (an example of which will show up tonight or tomorrow), what you put on the sheet you're allowed to bring in is up to you.
It will be important that you manage your time -- don't get stuck on any one problem too long, since you have the freedom to skip two of them. If you really don't know how to go about a problem, don't freak out: just pick another one. Choose your problems carefully, and start with the ones you think are easiest.
