The relative weight of each problem is indicated next to the problem number. Most credit will be
given for algebraic work. Do not insert numerical values until you have a final algebraic answer
inside a box. If you don’t know a particular constant, use a symbol to get partial credit. It is
almost impossible to award partial credit if you insert numbers too early. If you get stuck on one
problem, go on to the next and come back to the difficulties later in the exam period. Do not
leave early until you have completed everything. Do not quit! Never, never, never quit!! As
usual, before you start to manipulate equations and numbers you should
think for a moment
and
make sure that you have a general sense of the important features of a problem. Finally, please
do not violate the first and second laws!

There is no need to compute precise numerical results – ballpark values are
ok.
Points will be deducted for answers with insane units (e.g. the final
temperature is 19 kg*m).
Stuck? Approximate, approximate, approximate.
