Question: How to interpolate roots for a curve expressed in numerical arrays

I'm solving a system of ordinary differential equations numerically, I used the dsolve(system,numeric) to do it. I have also plotted the solutions. Now I want to know where does this solution cross zero and use this value for later computations, is there a way to do it?

This question is, as I think, equivalent to how to find the roots for a curve expressed in numerical arrays.

Thank you!
