A blast wave passes through still air at $300 \mathrm{~K}$. The velocity of the air behind the wave is measured to be $180 \mathrm{~m} / \mathrm{s}$ in the laboratory frame of reference. Determine the speed of the blast wave in the laboratory frame of reference and the stagnation temperature behind the wave in the laboratory as well moving frames of reference. You will find the following relations useful:
