 P: 61 1. The problem statement, all variables and given/known data I wish to know what is the best angle that can make an object go furthest. 2. Relevant equations No idea... Wiki is not helping... 3. The attempt at a solution I can not find anything on Google...

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.

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.

You still cant see the solution to your answer because you dont 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...
