Re: rads
There are 2π radians in one revolution, and 60 seconds in one minute.
To answer this, you need to convert the number twice. For example, you could convert first to revolutions/second and then to radians/second.
You could also convert to radians/minute first, but I think the first way involves easier numbers.
Why did the vector cross the road?
It wanted to be normal.
