REMARKS ABOUT HOMEWORK ONLINE:
Give your answers with 3 significant figures in the units indicated.
Powers of 10 should be in E format with no spaces. Example 3.14E9
HW03:08 (4.P.042) part a) and b): Any file you download gives you credit.
The figures are not graded.
HW04:12 (6.P.054): Use momentum and kinetic energy conservation for an
elastic collision. As a shortcut the relation v(2,f)-v(1,f) = v(1,i)-v(2,i)
could be used.
HW05:05 (7.P.033): Typo: Mass of spaceship is 30,000 kg, not 3 x 10E43 kg.
HW07:07 (11.P.004): Typo: Aluminum coefficient of linear expansion is
24 x 10^{-6} 1/C.
HW09:10 (13.P.067) part a) and b): 'Object drops before stopping' in this
problem means that the object oscillates and that its speed is zero at its
lowest point.
HW09:03 (13.P.008) part a) This is a straightforward calculation but
WebAssign grading contained an error.
The WebAssign error has been corrected as of Nov 7
morning. All your submitted answers are regraded and you get credit if any
of them were correct.

REMARKS ABOUT EXAM AND EXAM REVIEW
The week before exam2 the workshop will consist of HW10-problems,
a quiz and exam-review.
Be prepared to ask some questions about old or new problems that have been
bothering you.
If you do not have questions there is nothing to review.
_____________________________________________________________________
CALCULATOR.
If you have a graphing calculator, you may bring that to the exams.
However, the best type to have for the exams would be a non-graphing
scientific calculator.
That will have all of the functionality that you will need.
CELL PHONES.
You should not have a cell phone on you during the exam.
Please keep your cell phone in your backpack or coat and leave your
backpack and coat near the wall of the exam room away from any seat.
At your seat you should keep calculator, pencils, one personal
note-sheet and RU-ID.

Make your own sheet with formulae and notes to bring to the exam.

REMARKS ABOUT EXAM WEEK
