Answer
(a) The component of the acceleration vector which is parallel to the velocity vector is pointing in the opposite direction to the velocity vector. Therefore, the object is slowing down.
(b) The component of the acceleration vector which is perpendicular to the velocity vector is directed to the left of the velocity vector. Therefore, the object is curving to the left.
