Or... something like that. Originating from an accidentally misfiled thread, I'm trying to find the t in this equation; [math] s = {v_0}t + \frac{1}{2}at^2 [/math] Normally I'd try to shuffle the values around, adding, subtracting, dividing etc. until I ended up with what I wanted, but I've long since forgotten how to deal with multiple exponents and barely remembering the terminology {let alone in English} didn't help finding an answer either. Would someone be so kind as to give me a pointer or two how to deal with this?

Hello everyone. While this isn't for homework perse, I've got a simple question that has been frustratingly difficult to dredge out the answer/formulae to. How can I calculate the time it takes an object to rise and fall from elevation A to elevation B at initial upward speed of X units per second and gravity of Y units per second? My Google-fu has failed me, so I'd be appreciative of a working method for this. {Edit: And I've apparently posted this in the wrong forum. Go me. Blah.}
