A \(0.5 \mathrm{~kg}\) ball moving with a speed of \(12 \mathrm{~m} / \mathrm{s}\) strikes a hard wall at an angle of \(30^{\circ}\) with the wall. It is reflected with the same speed and at the same angle. If the ball is in contact with the wall for \(0.25 \mathrm{~s}\), the average force acting on the wall is
