1. Rube Goldberg Project

2.  Peter Calkins Outstanding Organizer  Andy Mihalik Courageous Calculator  Josh Adams Captain Carpenter  Blake Hanson Dashing Designer

3.  A marble is dropped into a piece of tubing the marble then continues to hit a hot wheels car.  The hot wheels car goes down a ramp and ramps into a ruler which spins and hits another ruler.  This ruler in turn cuts a piece of string that is wrapped around a banner dropping down a POWER T.

4.  Step One (marble collides with car)  mgh = 1/2 mv²  v = √(2gh) = 3.6 m/s  m₁v₁ + m₂v₂ = m₁v₁’ + m₂v₂’  v₂’ =.5625 m/s  Step Two (car goes down track)  mgh + 1/2mv² = 1/2 mv₂²  v₂ = 2.89 m/s  Step Three (car collides with ruler)  1/2mv² = 1/2 Iω²  ω = 18.9 rev/s

5.  Cutting the string connected to the banner  Stability of the device  Connecting our device to the other groups

6.  Project was fun but required a lot of effort  It was interesting to see how the principles of physics work out in real life
