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!

When you step in a dog turd, you scrape the **** from your shoe.
What's the point in being decent to the dog?

"Cassini had observed the moons of Jupiter between 1666 and 1668, and discovered discrepancies in his measurements that, at first, he attributed to light having a finite speed."
