Physics 102 - Suggested Extra Problems

Several people have asked for a list of suggested problems, aside from the homework, that would be particularly good to attempt. Here, I'll provide a list of problems from Tipler (either odd-numbered ones, so you can check the answer in the back of the book, or else the numerical answer is given here), but I'd also suggest that you could look at one or more of the alternate textbooks for additional problems and worked examples. I'll try and update this list as the term progresses...
