Actually on #18 did you forget to put the velocity in the first part? 0 = xtanθ/v -1/2g...

No originally it looked like [itex] v_0\tan(\theta) x / v_0[/itex] so it is not forgotten.

Oh right, I forgot to cancel the v0 when using the projectile equations. Thanks again!

Np. Can you see the advantage of doing your formulas by youself? Now you could design the optimal catapult for your needs and constraints(is that the proper english word?)
