_____________________________________________________________________________
PLEASE NOTE THE FOLLOWING
• Once you have opened the exam on the Gradescope, you have a maximum of 3 h to upload
your solution, including 1 h extra beyond 2 h exam duration to account for any issues. As 1 h
grace period is given, no exam will be accepted after the end of 3 h period. Start uploading a
scanned copy of your solution at least 15 min before the deadline to ensure you are not
locked out.
• Upload a clear scanned copy. If the scanned document is harder to read, you will receive
credit based on what is visible. It is your responsibility to make sure your uploaded solution
is legible.
• This exam has three problems with multiple sub-parts. The credit for each subpart is
indicated. Total credit is 40 points.
• Credit will be given for problems worked correctly even if the correct numerical answer is
not obtained. Be sure to indicate clearly how you are approaching the problem. Answers
obtained in correct algebraic form with defined variables and parameters (with appropriate
units) will be given full credit.
• There are no long or tricky answers. If you find yourself doing anything long or tricky, stop
and reevaluate your approach. In general, getting the correct answer to one sub-part of a
problem should not depend on solving the other parts of the same problem, although you may
need to use information given in another sub-part.
• Students who violate the university or class policy are subjected to disciplinary penalties,
including the possibility of failure in the course and/or dismissal from the University. Details
