For all of you college students, here are the mastering physics solutions. I found these useful more for getting the correct number, because we all know that the stupid online questions NEVER accept your answer whether it's right or wrong Smile
Just an FYI: in case you aren't already aware, the actual numbers will probably be different on the online questions. But this solution manual gives you the steps and formulas you need so all you have to do is plug in numbers. If you made it this far, you can do that much.
