2. The Team

3. The Project We were given the task of making a rollercoaster.
The object must stay on the “coaster” for close to 15 seconds.
We spent roughly $20 on random parts and different types of projectiles.

4. Continuing on… We decided to use a BB as our projectile.
We tested various objects such as marbles and paintball tracers.
The BB has less mass and is smaller than the marble, thus it fits through the small pipes easier.

5. How It Works
The BB is placed at the top of the apparatus, where it has about 3.17 E-3 Joules.
Entering the funnel it is going about 1.65 m/s.
It rolls down the first half-pipe into the first layer.
Its potential energy is converted to kinetic and the projectile has just enough momentum to make it to the end, and thus the next level.

7. How It Works
The BB is placed at the top of the apparatus and dropped.

8. Midway…
The BB travels down the first funnel and through the layers of pipes until it reaches the plastic tubing.

9. The End
Once out of the tubing, the BB reaches a funnel and spirals around until the base, where it stops.

10. In Conclusion:
We spent approximately hours building and testing the device.
We encountered many obstacles along the way, including not meeting the time constraints and giving the ball too much speed.
