Physics 9A Section A
Homework For Spring 2002


April 1, 2002

Answers to many odd exercises and problems are in the back of the book. When even numbers are assigned, solutions and answers will be provided at some point during the week. Homework is not collected, but it is important that you do the homework. Quizzes and midterms are largely based on homework and discussion problems.

Currently, the solutions are posted in MS word format. Each problem has its own solution file. I'm working on a better format for posting, but this will have to do for now. Let me know what you think. Also note that the problems will probably appear out of order when you click below. If I am missing a problem, let me know.

I have also included a .zip file for easy download. This is the next best thing to having all the solutions in one file. You will have
to unzip this using WinZip or some other utility on your end. Once you have downloaded all the files, you can create your own master file
by cutting and pasting.

Homework 8 should be done by Friday June 7, 2002:

Assigned Monay April 15, 2002; Solutions Posted Thursday April 18, 2002 around 7:30pm

Please keep in mind that the book is rather sloppy with the "A on B" force
notation we are using. Always try and translate the forces in your
own force diagrams to the "A on B" format. This will help with your
bookkeeping as well as your understanding as you learn this material.

Since the solutions I post are directly from the publisher (and not my own
hand-crafted solutions), you will notice this notational sloppiness in
the solutions themselves. Sorry for the inconvenience. Remember, if you
have any questions or comments, don't hesitate to email me or come to my
office hours.
