Replying to Physics Help

So I'm just doing this for fun, trying to calculate the pontential distance traveled of a jump (I'm think about this for a biking application but im sure it could be used for skiing as well). I havn't done physics since high school so I don't even know where to begin. I would think the following variables would apply: Gravity (-9.8m/s), velocity, mass of object (maybe?), angle of jump, air resistance (friction coefficient for air). I would think you would be able to figure it out from these. anyone know how to do it?
