PHYS-2020: General Physics II Problem Set 1, Spring 2012 There are 10 problems you are to complete via the web at http://capa.etsu.edu/ You will gain access to this set by typing in your CAPA Student Number and CAPA ID which will be supplied to you. These problems will be graded and must be completed by 6:00 p.m. on Friday, February 3, 2012. Start working on these problems immediately Don’t wait until the last day to start them. One never knows when the network will go down, and you will not be able to use this as an excuse for not doing your CAPA problems. As a matter of fact, there will be no allowed excuses for not doing your CAPA homework. The following problems will not be graded, but should be done for review. These prob- lems are from your textbook (College Physics, 9th Edition, Serway & Vuille). The solutions are posted on the course web page. Try to work these problems out by yourself before looking at the solutions I have supplied for you.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
