The story. In 1992 we told a textbook sales rep that we didn't like the Dynamics books. She said "Write your own." Most people said "Don't write a book. It's too much work, no-one will appreciate it and it will probably lose money." Saunders contracted the book and then sold it to Oxford. Now it's ours. Most years we work together for a month or so in Ithaca, Finland, or Bangalore. We re-organized the book 4 or 5 times and added a Statics book because students needed help with vectors and free body diagrams. Various pre-release versions have been used at Cornell and elsewhere about 25 times. It has had about 40 external reviews. The table of contents, preface and introduction show our intentions.

Use it for a course? Ask.

Help us:

        1) Add to the solutions manual? We'll tell you how.

2) Suggestions are welcome: Errors, things that are confusing, things that are hard to find. Give us some clues about what you don't like.

3) Make money if you are the first to find an error: $1.00 for math errors, $5 for real errors (with suggestion about how to fix). How? List errors like this (if John Smith is your name and the date is 2/15/14):

Sect 13.2, pg 642, par above "More about pendula". -John Smith 2/15/14
In the argument of the exponentials change    gt/l     to     +- sqrt(g/l)t.
