A normal shock propagates at \(2000 \mathrm{ft} / \mathrm{s}\) into the still air in a tube. The temperature and pressure of the air are \(80^{\circ} \mathrm{F}\) and 14.7 psia before "hit" by the shock. Calculate the air temperature, pressure, and velocity after the shock, the stagnation temperature and pressure relative to the shock ahead of and behind the shock, and the stagnation temperature and pressure relative to the tube ahead of and behind the shock.
