PHYS-2020-201: General Physics II
Problem Set 4, Spring 2008
There are 8 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 Wednesday, April 23, 2008. 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 problems
are from your textbook (College Physics, 7th Edition, Serway & Faughn). The solutions are
posted in the course reference binder at the (i.e., Circulation Desk) in the Sherrod Library.
Try to work these problems out by yourself before looking at the solutions I have
supplied for you.
