Correct me if I am wrong -
(a) While doing circular motion car is doing pure rotational motion as it rotates around a fixed axis [i am talking about motion of real car which turns its position]
(b) As it is moving friction is only force helping it to do so i.e. friction provide centripetal force.
(c) As being only force - if this force is applied on centre of mass of car it must give me translational component of motion - which obivously not zero.
So Why is circular motion is pure rotational?
Whole Question is based on the following statement of book
We can obtain the translational component of their motion by taking the mass of the whole system to be concentrated at the centre of mass and all the external forces on the system to be acting at the centre of mass.
[I think this statment is wrong]
