Energy Equations Assumptions: Mbigball >Mmarble Perfectly Inelastic Collision- mbbvbball + mbvb= (mbb+mb)(vboard) vball=mgh=0.5mv2 vball=sqrt(2gh)

Energy Equations PEi=PEf Mgho=0.5mvf2 Mmgho=0.5mmarblevf2

Energy Equations Tension m1- mass of cup (with dominoes) m2- mass of gate m1>m2

In Conclusion Our Rube-Goldberg device’s purpose to to perform the designated tasks and result in moving the gate for the car. This device includes many actions which can be explained using equations learned in EF 151. Pretty cool project, it was fun.
