Projectiles Practice Problems

I've uploaded the solutions to the projectile practice problems we did class with the lottery game. I'm posting the Period D version and the Period C version, which are practically the same, by hey, why not post them?  By default, all of the problems that I skipped are also included, but I left them in the document in case you want to practice some extras.

It is essential that you know exactly how each problem is solved, including knowing why every single variable was what it was.  If there is something you see bu don't understand, see me for a quick explanation.  If there are lots of things you don't understand, see me for some longer extra help!
