    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.

    The Final exam3 will be December 19 at 8:00am-11:00am in CAC Gym Annex.
    The day before exam3 (Dec 18) a day-long (10:00am-8:00pm) help session will be held in room SRN-232 (workshop room).

    The Final exam covers all material of the course.
    There are 30 questions. The exam is 3 hours. At least half the questions will be about the material not covered in exam1 and exam2.
    You are allowed to bring 2 sheets of notes in your own hand writing.
    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.
    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.


    There will be regular labs as well as online homework during the exam week.

    Give your answers with 3 significant figures in the units indicated.

    Occasionally, announcements about the physics 161 course will be sent out by e-mail.  I have down-loaded the "official" e-mail addresses from the University roster.  Be sure to check your "official" e-mail address for new messages.If your e-mail address has changed or is not listed with the University roster,  let me know.
