This is what you want it to do…

The intent of the event is to have a falling mass propel a cart carrying an egg down a track as quickly as possible and end up with the egg as close to the terminal wall without…

as quickly as possible!!!

ScoringRun Time -> ‡ complete stop

Stopping Distance ->‡ Distance from the pointed end of egg

to centerline of the terminal barrier (cm) (NEW)

‡ Lowest possible value: 0.1 cm (NEW)

Performance Value -> ‡ 2 x Run Time + Stopping Distance

Whatever run gives you the best ranking is the one counted

Building suggestionsFirst and foremost, build early, practice, log, and calibrate as many runs as possible.Use a plastic egg filled with any material to around 65 gAlways build just under/over the dimensions!!!! Make the transport as light as possible Perhaps try some different floor surfacesDid I say calibrate?Strongly consider using aligning devices since you need the transport to go as straight as possible
