Neglecting air resistance, the horizontal component of the projectile's acceleration is zero. This is because once the projectile is launched, there are no horizontal forces acting on it (assuming no wind or other external factors), which means there is no change in its horizontal motion, i.e., constant velocity. Therefore, the acceleration in the horizontal direction is zero.
