You forgot to convert 3000 rpm to radians/s.

No haruspex,

I have converted it in the second last line.
Please see.

Looks to me like you converted rpm to revs/sec, and you converted n revolutions to 2nπ radians, but I don't see any conversion from revolution rate to radian rate. (The pi's should cancel.)
