The Engineers:

Introduction Our teams goal was to construct a roller coaster that would have a 15 second ride. Our materials were found at Ace Hardware, Lowes, and scraps in the Estabrook work room. We bought 2 funnels, screws, a marble, and wood.

What Happens? The marble is released into a series of PVC pipes before falling into a shorter PVC pipe. This leads into a funnel where it spins and falls into the a final PVC pipe. Ultimately, the ball rolls into a final funnel and spins through it resulting in the marble landing on the ground.

Energy Conversion Gravitational Potential Energy to Kinetic Energy mgh=0.5mv m/s 2 *.4572m=0.5v 2 V=3m/s At the end of each pipe 9.81m/s 2 *0.0381m=0.5v 2 V=.865m/s

Conclusion Over all, we spent 4-5 hours building the actual project. Another 4-5 hours were spent on the paper, calculations, and preparation for this presentation. Our group consisted of 5 future engineers.
