2. Overview
Our project consisted of shooting a marble up a foam insulator pipe, then having it roll down a sequence of “zig-zags” to knock over a series of dominos in order to finally have our mouse-trap-launcher punt a football.

5. Energy Conversions
1/2kx^2  1/2mv^2
1/2mv^2  mgh

6. Momentum (for dominos):
mgh  1/2mv^2
Momentum (for dominos):
mv1  mv2  mv3 …

7. Finally,
1/2kx^2  1/2mv^2
to successfully launch the projectile.

8. Conclusions
After completing our project, we decided that simple - looking devices still require a large amount of work and brainstorming.
Our device does in fact launch a projectile intended with few inconsistencies.
One improvement would be to calculate an angle of launch and attempt to shoot our projectile a certain distance.
