Title: Projectile Motion 0.5

A projectile is launched at a given angle and velocity. What is the initial velocity in the horizontal/vertical direction.

This is my first pull request; thanks so much to @petercollingridge for all his help answering my questions.

I'm thinking this would branch off the basic trig exercises and lead into more advanced physics exercises.

Please give me feedback
