Energy Conservation Summary Car at Top of Ramp E=(mgh) Car Rolls Down Ramp (mgh)=.5mv^2 Car hits Stick activating PE of Pipe Pipe Raises Ramp, Giving Ambulance PE (mgh) Ambulance Rolls Down Ramp (mgh) =.5mv^2 Marbles Fall from Pipe (mgh) = (.5 mv^2) Marbles Activate Mousetraps Mousetraps Pull Box (.5kh^2)=(.5mv^2) Allows Guillotine to Fall (mgh) = (.5mv^2)

Conclusions 1. Don’t be afraid to vary from original ideas. 2. Better communication and planning would have increased productivity. 3. Mousetraps can be extremely painful.
