RULE
:
You are allowed to use
almost
any resources (books from the
library, etc.) to solve these problems.
THE EXCEPTION
is that you
MAY NOT
COLLABORATE WITH ANY OTHER PERSON
in solving them! If you have questions or
difficulties with these problems, you may consult with me
, but
not
with fellow students
(whether or not they are in this class!) or with other faculty. You are bound by the TTU
Code of Student Conduct not to violate this rule! Anyone caught violating this rule will,
at a
minimum
, receive an “
F
” on this exam!
INSTRUCTIONS:
Please read all of these before doing anything else!!!
Failure to follow these
may lower your grade!!
1.
PLEASE
write on
one side
of the paper only!! This may waste paper, but it makes my grading
easier!
2.
PLEASE
do not write on the exam sheets, there will not be room!
Use other paper
!!
3.
PLEASE
show all of your work, writing down at least the essential steps in the solution of a
problem.
Partial credit will be liberal, provided that the essential work is shown. Organized work, in
a logical, easy to follow order will receive more credit than disorganized work.
4.
PLEASE
put the problems in order and the pages in order within a problem before turning in this
exam!
5.
PLEASE
clearly mark your final answers and write neatly.
If I cannot read or find your answer, you
can't expect me to give it the credit it deserves and you are apt to lose credit.
6.
NOTE!!!
the setup
(THE PHYSICS)
of a problem will count more heavily in the grading than the
detailed mathematics of working it out.
PLEASE FOLLOW THESE SIMPLE DIRECTIONS!!!!
THANK YOU!!!
NOTE!!!! WORK ANY 5 OUT OF THE 6 PROBLEMS!
Each problem is equally weighted
and worth
20 points for a total of 100 points on this exam.
Please sign this statement and turn it in with your exam:
I have neither given nor received help on this exam

Signature
1.
See the figure.
Two masses,
m
1
and
m
2
are connected by a massless, inextensible cord of
length
that passes through a hole in a horizontal table. Mass
m
1
moves without friction on
the table top, in a curved path as shown, while mass
m
2
oscillates like the bob of a simple
pendulum. Gravity is acting downward. Use the generalized coordinates suggested in the
