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
Both parts will be due at the beginning of lecture on Fridays.
- 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.
No homework will be accepted after the solutions are released on BlackBoard
(at 12:00 PM on the Friday when it is due).
