Lecture HomeWork 4

Physics 121, Fall 2010

Prof. E. F. Redish

Lecture homework consists of 2 parts:

• 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 point each. 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
• The second part is one of the problems from my collection. It should be prepared carefully and neatly on paper (preferably on a computer and printed out). It is worth 5 points.
  • Please be certain to put your name and section number on every page
    and to NOT CONNECT THE PAGES with staples, clips, tape, or dogears.
    Connecting them may result in you homework being damaged or destroyed.
