2. Team Picture

3. The Goal  To build a rollercoaster that transports a device from one point to another  The materials we used to build our rollercoaster were some clear tubing, duct tape, wood, a funnel, and a cardboard box  Overall, the total cost came out to be around fifteen dollars

4. Description  Device is a small metal ball  Begins with a long, slow spiral  Empties into a funnel  Leads into a parabola (the trunk)  Comes to rest at the bottom of parabola

5. The Elephant

6. Calculations  Potential energy at the top  Assuming no friction, we can use COE to find velocity at the bottom of the box  Likewise, we can find speed at the bottom of the parabola  Also, we can estimate the height the ball will go up the parabola

7. Conclusion  We originally had many different ideas  We were short on time with all of our ideas until we decided to use a parabola  We did not have too many problems, just getting good support with the duct tape  We had a good team and got the job done
