(non-school question!) Assuming same force each throw, best trajectory for distance?

I want to be able to throw a basketball the greatest distance possible. assuming i throw with the same force each time, what angle should i release the ball at? In addition, instead of an overhead throw, if i start with the ball in front of me and wing it down and around into a throw motion, will that not give me a greater force to throw the ball with? This is not a school question, i am being tested and i need to throw as far as i can.
