When moving through the air, a ball experiences a drag force proportional to the square of its speed. Just before a volleyball player strikes the ball, it was moving horizontally with a speed of \(V_{1}\). After being hit, the ball moves vertically upwards with a speed of \(V_{2}\) and an acceleration of \(a_{2}\). Determine the acceleration of the ball just before it was hit.
