   Good day, I'm Fraser and I'll be joining you for a while.  I apologize for
the title of this message, I'll admit it was a rather shallow attempt to get
people's attention, but one has to do these things when one is new.  I was
actually here once before, but didn't realize that the REPLY command sent
mail personally, I should have used FOLLOWUP.
   In any event, I'd like to submit to the members of this base, who no
doubt are fairly competant in physics, a humble little 1st year test question
that has caused me much chagrin.  I'll explain why it annoyed me next time I'm
on, this time I will just post it and see what answers people give.  I probably
shouldn't have admitted to being 1st year, it will put me at a disadvantage in
any arguments, but oh well.  Here is the question, which we were expected to
solve in less than five minutes.

    Part a:  A ramp of height h is on a table.  The ramp has no friction, and
at the bottom where it comes off horizontally.  The top of the ramp is at the
centre of the circular table.  If a particle slides down the ramp, with what
velocity will it come off?

    This part is of course easy, and you don't need to know anythihng except
the height of the ramp to answer it.  Focus on part b.

    Part b:  Now another particle is slid down, but this time the table has
a rotation about it's axis (perpendicular through centre).  You are given
the rotational velocity w, and the radius R.  What are the radial and tangental
components of the velocity?

   I won't say anything else about the quesiton until I get a responce.  Hope
to chat again soon.  Oh, a question:  How can I make my name something more
reasonable than "qucdn 3363379"?  It seems rather impersonal.
