Question: Cannot evaluate the solution

Question:Cannot evaluate the solution

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 V0 are constants which can be any number except V 0  which 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);
Please Wait...
