Since the accelerations are constant (like due to gravity), the Kinematic Equations of Motion are the relevant equations:

What level are you in school? Are you taking a physics class now?

You can also google Projectile Motion to get an idea of how to apply those equations.

Post some of your work and ask specific questions if you have them after reading through the material.

not really helping at all... since i am a 9th grade... i have no clue what is these symbols about! even i do, i still don't see i can find the answer to my question...

If you want to learn id say the best advice is learn how to use those equations. They really arent as bad as they look.

even i do, i still don't see i can find the answer to my question...

You still can't see the solution to your answer because you don't know what youre looking at!

Fair enough. Yeah, you'd need at least basic calculus to do the actual optimization of the equations. Here's another wikipedia.org page that has some good info, including the effects of wind drag:

And I think you may be able to use the Excel calculator at the bottom of that article to answer the question by using Excel...
