A point moves along an arc of a circle of radius R. Its velocity depends on the distance covered s as v = a√s, where a is a constant. Find the angle a between the vector of the total acceleration and the vector of velocity as a function of s.

The problem with the answer is that it finds the angle between tangential acc(same as direction of velocity vector) and centripetel acceleration..But the question is about finding the angle between tangential acceleration and total net acceleration not centripetel acceleration..If the direction of both centripetel and net acceleration coincides that means tangential acceleration must be 0 which is not the case here..I know the answer is right according to the answer key given in Irodov book but don't you think its wrong..If its my mistake please rectify me..Thanx in advance
