I can do it if I have one ODE - see please the picture

But if I have 3 ones - see please the attach Prime 6

Here is one way to achieve that 2-argument function

But you have to keep in mind that the whole solve block gets recalculated from anew for every single time value you want to evaluate the function for - even though you don't change the initial velocity "v". So this function is not best suited for plotting as its really slooooow!.

A better way probably is to settle for one initial velocity "v", evaluate the solve block only once and assign the result to single argument functions:
