Mousetrap Catapult for Acuracy

[justin8606]

I'm trying to make a catapult to test the accuracy of 4 different textured objects. I have to shoot from 3 meters away or farther. What can I do to improve accuracy?

Your question doesn't really make sense...Accuracy is how close to your target you shot the object. Nothing to do with the object. Though objects with less air resistance will go further. (As long as you aim well)

To PI the projectile/object design can make a difference to one's ability to be accurate - we put flights on arrows and darts to help steady flight, a cricket ball polished on one side and rough on the other can swerve and swing (admittedly it's spinning as well as flying thru air), and I would find it much easier to throw a ball of scrunched up paper into my bin than a paper aeroplane.

 

To OP I think to get much help you need to be more forthcoming in the constraints and desired results of your experiment.
