Forget it that was a typo i meant the unit vectors which change with time as the body moves

I meant a coordinate system where the base vectors are changing with time

So how can we express quantities like average velocity and average acceleration in a changing co-ordinate system like the plane polar coordinates system

It's just for an arbitrary motion. Yes, the quantity being integrated here is velocity in plane polar coordinates

we can express theta as a product of the angular velocity and time thus plugging this in space of theta in the above equations we can express r hat and theta hat as a function of time. But i am having problems in integrating them and again converting them back to the terms of r hat and theta hat...
