This is an excellent book. It comes with theory, solved problems and even some physics poems.<br>If you are looking for a compilation of mechanics problems, then this book suits for you.<br>But, if you want a theory book, I would recommend another one, such as Taylor or Goldstein.<br>Also, the title says it is an introduction, but I would not recommend it for a freshman. I think it has an aproppiate level for a second year.
