Hello!

I have a problem with solving of my differential equation second order. Whenever I Try to draw a plot of it I have this "Warning, cannot evaluate the solution past the initial point, problem may be complex, initially singular or improperly set up".

All "A", "B", "C", "K" and Vare constants which can be any number except Vwhich is only a positive number.

 

restart;
v[0] := 500; C[0] := 1; B[0] := 1; K[1] := 1; C[1] := 1; K[2] := 1; C[2] := 1; eqn := x(t) = v[0]*t-C[0]*B[0]*K[1]*C[1]*(D(x))(t)*t^2/(1+C[0]*x(t))^2-C[0]*B[0]*K[2]*C[2]*(C[0]*x(t)*((D@@2)(x))(t)-2*C[0]*(D(x))(t)^2)/(1+C[0]*x(t))^3;
sln := dsolve({eqn, x(0) = 0, (D(x))(0) = 500}, numeric);
plots[odeplot](sln, t = 0 .. 1);
