I actually just posted this in the physics subforum but realized that it is much more appropriate here. So I've got a good deal of the summer in front of me, and I've realized that I've wasted all of my time doing nothing. As a result, I've decided to do something productive and teach myself introductory physics using the extended third edition of Physics for Engineers and Scientists. Since I would like to attain a sound grasp of the material, I will attempt to solve the most challenging of the book's problems. I would like to know where I can find help when I will inevitably need it. Is there a site with answers and the work required to reach them? I looked on Cramster.com but discovered that the book isn't supported. I realize that I can post questions here, but I also realize that I won't receive answers immediately. Any help would be greatly appreciated. Thank you in advance.
