A closed cylindrical tank that is \(8 \mathrm{ft}\) in diameter and \(24 \mathrm{ft}\) long is completely filled with gasoline. The tank, with its long axis horizontal, is pulled by a truck along a horizontal surface. Determine the pressure difference between the ends (along the long axis of the tank) when the truck undergoes an acceleration of \(5 \mathrm{ft} / \mathrm{s}^{2}\).
