How'd i mess that one up...

6 * 3.1415 = 18.849" circumfrence

18.849 * 442 / 60/ 12 = 11.5 Feet Per Second

Wow, must have hit the wrong button somewhere. Thanks Cory.
Remember that this calculation is for the CIM's free speed. The motor will never achieve that speed on a robot because of load, so the actual output speed is probably something closer to 45/50% of this.
