You hear the sonic boom of a high-speed jet plane exactly 4.00 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 25.0 o above the horizon. Assume that the speed of sound at the altitude of the plane is 325 m/s. How fast is the plane traveling? What is the altitude of the plane?

Shock Waves

Shock waves are common in continuum mechanics, and their dominance is attributable to the fact that they are stronger (or even less) compressible. Substantial perturbations propagated as sudden dynamic changes of a compressible medium supersonically. Shock waves are all around us in our daily lives. Lightning, earthquakes, volcanic eruptions, and meteorite impact all produce them in nature. Even the earth, which is protected by its magnetic field, generates a shock wave as in solar wind that travels around 20 Earth radiuses. These shock waves might be either constant, linked to the body, or unsteady, i.e., moving around with time. All of the shocks mentioned above can be damaging, so precautions must be taken to reduce their impact.
