Lecture HomeWork 1

Physics 122, Spring 2011

Prof. E. F. Redish

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

• One part is to be done online in the MasteringPhysics (MP) environment. This includes a few MP problems plus a few problems from my collection. The MP problems will be exercises, worth 1 or 2 point eachs. You may use any hints that are available and you can do them as many times as you want. The problems from my collection are worth 2-3 points each. You only get to submit those once.
• 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.
