edit: lol.. I just don't see what we are to solve it with (and I doubt it is possible unless it is a tiny red ball that can be launched and then curved in the air... meaning I don't think it is poossible )
but hey, many things I have thought were impossible are not!
If you scaled it up so that the workspace would be greater, I think something could be made that launches a mini catapult to one side and then the mini catapult would launch a red ball towards the ending. As it is though I don't think it can be solved, even with a red ball.
