1. Team 2 Rube-goldburg Device Team Members: Nate Talbot, Elliott Walton, Stephen Gresham, and Arthur Knotts

2. Stage 1 All Energy is Potential U=mghK=½mv² m=mass g=gravity v=velocity U₁+ K₁ = U₂ + K₂ Then is Converted to Kinetic when the stopper is removed M=mass G=gravity V=velocity H=height

3. Stage 2 Projectile Motion Y=y₀ + V₀t +.5gt² X= x₀+ V₀t The Marbles fall from stage one and are shot from a ramp into a funnel Y=displacement on y-axis T=time g=gravity X=displacement on x-axis

4. Stage 3 Gravitational Potential EnergyU=mgh From the funnel the marbles are at the mercy of gravity and fall into a bag U=gravitational potential energy M=mass H=height

5. Stage 4 Tension and Torque T=maτ=Iα When enough marbles have fallen into the bag the pulleys are initiated and the track is pulled up τ=torque I=mass moment of Inertia α=angular acceleration r=radius T=tension m=mass a=acceleration

6. Part 5 Center of Mass We offset the center of mass in the box to erect the flag X=center of mass M=mass

7. Conclusion
