Hi guys,
How to solve following equation and get r(t):
r''(x,y)=1/2m * F(x,y)
r'' - second derivative on time
F(x,y) = eps * (1/r + x/r^2 + y/r^3);
r = sqrt(x^2+y^2)
r(t=0)=sqrt(x0^2+y0^2)
m and eps - constants
Thank you!

What do you mean by solving? You have r function. Can't you just get derivatives or r?

I dont think you can solve this, a relation between x and y, or x and t, or a direction of the force is required.

The function f(x,y) is know and calculated in each point on the surface (x,y). Do you think it is still impossible to solve this movement equation?
