Lecture HomeWork 8L

Physics 122, Spring 2011

Prof. E. F. Redish

Lecture homework consists of 2 parts. Some of the problems this week require diagrams and tools that are not available in MP. These will have to be done on paper.

• One part is to be done online in the MasteringPhysics (MP) environment. This comes in two parts. First is a few MP problems as warm-up. These are worth 1 point each and you can do them as many times as you want until you get them right. There are also a few problems from my collection. These are worth 2 or 3 point each and you only get one attempt at them. You should work them out fully before attempting to enter them. (They are given in the list below for your convenience.)
• The second part are problems from my collection. It should be prepared carefully and neatly on paper (preferably on a computer and printed out).
  • Please be certain to put your name and section number on every page
    and do NOT CONNECT THE PAGES with staples, clips, tape, or dogears.
    Connecting them may result in you homework being damaged or destroyed.
