THE ELEPHANTBy: Steven Beaton, Casey Brown, and Doug Lindsey

Team Picture

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

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

The Elephant

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

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
