   I am looking to get the speed of an object with physics being shot out of a cannon and cant seem to work it out, here is a capx of the general idea, any help would be greatly appreciated.

	3DGS, Speed = Distance/Time, so you need to determine the distance traveled by the cannon ball in a specific period of time, like every tick. Here is a modified capx: http://dl.dropbox.com/u/38038537/Speedofball_modified.capx This was just a quick and dirty example, and I'm sure there must be a more elegant solution (perhaps even built-in).

	The physics expressions 'velocity x' and 'velocity y' are probably what you are looking for. I am not sure how to combine them to give you a good indication of actual velocity but it can't be that hard (most of the people hare are maths geniuses anyway ;) )

	distance(0, 0, velocity_x, velocity_y) will give you the speed. angle(0, 0, velocity_x, velocity_y) will give the direction.

	See? I knew there would be a more elegant solution. Here is the capx again, with R0J0's information: http://dl.dropbox.com/u/38038537/Speedofball_modified.capx

	This is exactly what I was looking for, thank you. I never thought of using velocity like that. Totally makes sense.
