I need help with a problem for my AP online class, my teacher is a bigger idiot than Pacman Jones, and can't teach to save her life: Any help would be appreciated. You don't necessarily have to do it for me, but just show me which equations to use, and which variables mean what. Thanks in advance, I really appreciate it.

Equation for constant acceleration at^2 + v0t + s = 0, where: a = acceleration v0 = initial velocity of the object s = initial position of the object

Split your velocity into two components: an x component and a y component, and try to work it from there.

Things that need to be taken into account include terminal velocity (you would need the mass of the cannon ball), gravity in general (the cannon ball may be traveling almost straight down by the time it gets to the ground) Personally I would look into projectile motion equations. All projectiles proceed on a curve, you are just starting 60% of the way through the curve.

I have nothing to offer this thread in terms of an answer...but what does it say about me that I am curious to see what the answer is? I keep hitting refresh to see if someone has offered an answer...

That's what I'm trying to do, use the projectile motion equation, but once i plugged all the numbers in, the computer said the answer was wrong, but you get three shots at each problem.
