ROCKEt HeLp?

I’m fourteen and i’m really interested in rockets. I have been launching off the model rockets you can buy from hobby stores since i was 8. For a book report, i read the book October Sky and saw the movie. Now, i’m really interested in making my own rocket. Does anyone have any links or good book i can read to get to know enough about them to make a simple rocket? I’m really good at math and i’m a real good at science too. If you don’t have any links or any books that would really help, i can handle the equations, even if they’re for the nozzle. I was hoping i could make one out of metal…not just cardboard. Thanks in advance foryour help!

HELP! Just some little algebra problem I can’t figure out today.?

Here it is: A model rocket is fired straight up from groung level with an initial velocity of 100ft per second. the height “h” of the rocket after “t” seconds in flight if given by h=-16t(squared) + 100t.
(a) rewrite the equation for h by factoring the right hand side if the equation above.
(b)At what times ‘t’ will the rocket be on the ground?(This is especially good to know if you are standing at the firing location and do not want to get hit when the rocket comes back down.)
Please help!!!!! Sort of explain too. 10 points for who ever makes sense!
