So, honestly, to figure out this experiment, it is better to use a tube or round pen instead of the triangular block (because it is easier to find and easier to balance)
Now then, you simply gotta do is place the nickel right at the 1" point on the ruler for each trial and you will drop the quarter from 12" for each trial.
After wasting a few hours getting the ruler to not rotate while I launched the coins, I got a few sample results (this was calculated from the start position of the nickel)
______________________________________
Middle Trials (6")
T1: moved right about 0.5"
T2: moved left 1" and backwards 0.5" (-0.5")
T3: moved right 2" and backwards 0.5" (-0.5")
______________________________________
9" trials
T1: Right about 1"
T2: Right 0.5"
T3: around 0.8" foward
______________________________________
12" trials were all at 0" in change
______________________________________
The 12" trial requires more force for movement while the 9" trial gave the most positive changes forwards
