Hi
I am succesfully using NDSolve to find the solution of a 1D equation of motion:
This is a particle decelerating constantly in the x-direction. Now, I need to extend my problem, because the deceleration along x is actually not constant. It depends on both the x- and y-coordinate of the particle.
So the total problem is
[tex]
\frac{d^2x}{dt^2} = -200y - x\\
\frac{dy}{dt} = -2
[/tex]
So along x there is non-constant deceleration, and along y I have a constant velocity. Is it possible to solve such a problem in Mathematica?
Best regards and thanks in advance,
Niles.

Code:
solution = NDSolve[{x''[t] == -200, x[0] == 0, x'[0] == 100}, x, {t, 0, 1}];
ParametricPlot[{x[t], x'[t]} /. solution, {t, 0, 1}, PlotRange -> {{0, 100}, {0, 100}}]
So the total problem is

\frac{d^2x}{dt^2} = -200y - x\\
\frac{dy}{dt} = -2
