The car \(A\) is ascending a parking-garage ramp in the form of a cylindrical helix of 24 - \(\mathrm{ft}\) radius rising \(10 \mathrm{ft}\) for each half turn. At the position shown the car has a speed of \(15 \mathrm{mi} / \mathrm{hr}\), which is decreasing at the rate of \(2 \mathrm{mi} / \mathrm{hr}\) per second. Determine the \(r\)-, \(\theta\)-, and \(z\)-components of the acceleration of the car.
