The acceleration is always in the downward direction (given - j).
So when the projectile will be at maximum height, it will be just parallel to the horizontal and there will be no horizontal acceleration (infact never during the entire path).
However there will be the Vertical acceleration in the downward direction same as the initial acceleration.
So aT = 0
aN = - 32 j
