I don't really know what I know at this point. Sorry, I should have mentioned that air resistance is involved and that the quadratic model applies, -0.2*D^2*v^2.

I'm in one of those situations where my homework involves questions that I haven't seen before. I know the idea is that I'm supposed to "use what I have learned" to solve the problem, but I obviously haven't learned enough.

I'm not asking anyone to do the problem for me, really, it would just be helpful if someone could post a link to basic problem where a ball is being projected upwards and I have to find the max height, etc. taking air resistance into account. Essentially the use of newton's second law and air resistance.

I just need to see one sample problem worked through so I can see how its done... i guess...
