Hm.. Well, with t=10, the height comes up to 40m! So, I don't thing that's right! And another thing: haven't we gone back to the "wrong" equation? When t=0, h!=90..

I had to stick to h=4.9t^2+42t+110 because that is what was printed on my handout from my teacher. Anyway, I turned it in today for better or worse. Thanks for all your help!
