12/09 A copy of the solutions to Tests 4 and 5 is 
      now available at the Noble Library Copy Center.

12/05 There is an error on Old Test #5, MC
      question #10.  The correct answer is
      3.68 X 10^4 J, not 3.68 X 10^3 J.  This
      correction was made on the overhead during
      the test, but I forgot to make it on the
      key.  Also, MC question #12 is not relevant
      this year; we did not cover that topic.
      
12/02 Mike Grams will hold a review session in 
      PSF-123 on THUR night 12/04 beginning at 7:40.
      I will have an extra office hour on Fri from 
      1:40-2:30 (i.e. my Fri office hours this week
      will be from 12:40-3:30.)  However, I will not
      be in Help-Study on Thursday this week as I
      must attend a Master's Defense at that time.

11/13 Mike Grams will hold a review session in 
      PSF-123 on Tue night 11/18 from 7:30 - 9:30.
      I will have extra office hours (i.e. in addition
      to my usual office hours) on Mon from 3:00-3:40 
      and on Tue from 5:00-7:00 in PSF-462.

11/04 A copy of the solutions to Test 3 is now
      available at the Noble Library Copy Center.
      At the same time, I put copies of the 
      solutions to Test 2, which I had neglected
      to do after returning from Budapest.

10/20 Mike Grams will hold a review session (where
      you may ask questions relevant to the upcoming
      test) in PSF-173 on Wed night from 7:30 - 9:30.
      David Vonk will also hold a review session
      (once again, come with questions on the 
      concepts involved, don't just ask how to do
      certain problems) in PSH-352 on Wed afternoon
      at 4:30.  My office hours on Tues 10/21 will
      be extended.  Instead of the usual 3-5 PM, I
      will be available from 3-7 PM in PSF-462 to
      answer your questions on Momentum and Rotation.

10/01 From the afternoon of Fri 10/03, through the
      afternoon of Fri 10/10, I will be off campus,
      on a research trip to Budapest, Hungary.  The
      2nd test, on Mon 10/06 will be administerd by
      our TAs.  Your graded tests will be returned 
      in recitation beginning Fri 10/10.  Mike Grams 
      will cover my 12:40 office hour this Friday.  
      After that, my office hours will not be covered 
      until I return, probably for my 2:40 office hour 
      on Fri 10/10.  However, PSF-462 will still be 
      reserved for our class during my office hours.  
      You may still meet there and solve problems as 
      a group.  Next Wed's lecture will be given by 
      Professor Luanna Ortiz.   On Fri 10/10, the 
      lecture will be given by Professor Otto Sankey.  

9/24  Change to HW problem 16(b) from Chapter 5.
      In this problem, instead of solving for the 
      angle between the string and the horizontal,
      call that angle theta and assume that it is
      known.  Assume the speed of the rock is
      unknown.  Then solve for the tension in the
      rope and the speed of the rock.  (This change
      makes your algebra much easier.)  This problem
      is assigned on Fri 9/26.

9/16  A copy of the solutions to Test 1 is now
      available at the Noble Library Copy Center.

9/03  The old tests, with solutions, are now available 
      in the Noble Library Copy Center.
