This math problem

I always wanted those word problems to end with "dude can load x watermelons at z rate if the trebuchet crank is twisted 7/2pi With a max rotation of 27/2pi and a tension force of 180 newtons, if the projectile is ejected after 1.4 seconds how far will it land at max rotation and where will it land at 7/2pi rotation?
<_<

and then bombard them with watermelons.

I dunno, costco gets pretty good deals
