Solve the following differential equation:
x''+(c/x^2)=0 . Solve for x in terms of t.

Assuming x(t0) = x0 and x'(t0) = v0, see
http://groups.google.com/group/nl.we...3dead300de9aa3
to reduce this to
x' = sqrt( v0^2 - 2 c (1/x0 - 1/x ) ) which is another 'simple'
differential equation.
Just write it as
dx / sqrt( v0^2 - 2 c (1/x0 - 1/x ) ) = dt
and integrate between t0 and t to find t(x).
Then 'simply' invert to find x(t) ;-)

HAHAHAHA! What a classic!
I gotta keep that one!

Yes, keep it with the pictures of your daugther.

Dirk, have you no decency at all?. ... Sheesh!

[Dirk, the kacksacker and **** scraper]
When you step in a dog turd, you scrape the **** from .
your shoe. What's the point in being decent to the dog?

Sheesh, Dirk! First you tell the world that you hate and
ridicule a grieving dad for the tragic loss of his daughter
and now you say that you hate animals too... My gawd,
Dirk, are you drunk or loaded this Saturday eve and/or
are you having mental problems because it is full moon
tonight?. --- No wonder they fired you, with you exhibiting
such a calloused, sociopathic outlook on life.
BTW, you are a daddy too, aren't you?
