So I got 2 functions, both describing the y position of an object moving with a certain acceleration and air drag(tough a very simplified one) as a function of the time t.



Now I want to get a function that gives me the time when the two objects meet, so when the functions intersect. So basically: t=whatever

I've tried solving it around a bit myself, and I even tried the Wolfram Mathematica of a friend of mine, but with no success.

Any help? Oh and could you include in your answer HOW you get to the solution? I want to understand this, not just get a solution and then forget about it.
