Expert Response from Jennifer Heldmann:
Nice work!  Great idea to use the angle protractor to measure your  angles.  What do you plan to use as your impactor, and what kind of material will you impact?  Good to have the stopper inside the cannon with the spring - make sure the stopper works well so that your experiment is safe!
