This exam is closed book, but you are allowed one 8.5" x 11" (doublesided) page of
handwritten notes. You may use a calculator, but not for graphing.
Remember to circle all of your final answers.
Read through the entire exam to start. Work to maximize your credit  try to obtain at
least partial credit on every part of every problem. Do your work clearly so we can easily
follow. Show
all
work, using the front and back sides of this exam paper. If you do not
show relevant work for any part of a problem, you will not be awarded any credit, even if
the answer is correct. If you recognize that an answer does not make physical sense and
you do not have time to find your error, write that you know that the answer cannot be
correct and explain how you know this to be true. (We will award some credit for
recognizing there is an error.) Do not get bogged down in algebra  if you have enough
equations to solve for your unknowns, box the equations, state how you would finish, and
move on (you can go back and complete the algebra later if you have time).
And if you have questions about the interpretation of a problem,
please ask!
