I have uploaded an Interactive Physics problem on 192.147.239.87, now
called physlab.catlin.edu.  Here is the problem.  A small satellite is
orbiting a larger planet but in this problem G is not the ususal value but
has been assigned a value of 10 and this is the problem.  Students are
asked to find G based on the information given in the problem.

You will find this problem under the Mech Library and listed as orbit.ip.
Download the problem and run it under IP.  Allow the satellite to make
just ONE orbit.  Print out the results, duplicate and you have a neat
problem for students.  I have had students come up with interesting
methods of finding that second focal point.  That is essential to solving
the problem.  At least none of my students found another method.

Good hunting.

BTW, the problem was generated on the DOS version of IP but it should run
under a Mac.  Let me know if you have any problems.
