Not sure where to put this topic, here or Assemblies so I'll
try both.
I read about a trebuchet simulation to teach CosmosMotion that flings a ball on a rope. The arm of the trebuchet pulls the rope that has a loop on one end that attaches to a hook. The ball is pulled through a trough untill it begins to become airborne. At a point of the arm's arc, the ball/rope disconnects from the hook and flies off into never/never land.
What I'm trying to figure out is how to set up the asembly mates, both how to keep the ball in the trough until it can fall out and the loop/hook that comes loose.
Any ideas?

No mate are required to achieve what you are attempting. While setting up the motion study you need to turn on both gravity and contact. When you place your parts in the model, place them so they are in their initial states without using any mates. You also need to make sure they are not interfering with other components in the assembly. Another way to approach it would be to use mates to locate your parts, but then suppress them right away in the motion study.
You should post a video of the Trebuchet in action. It is quite amazing what one can do with the new tools built into Solidworks.
