Solution B

Answered 1 year ago

Step 1

1 of 3We will use the formula:

$\begin{align*} \textcolor{#4257b2}{\sin\dfrac{\theta}{2}=\dfrac{S_s}{S_a}\quad\quad (1)} \end{align*}$

where $S_a$ is the speed of the aircraft, $S_s$ is the speed of sound and $\theta$ is the angle of the sound cone.

We are given:

$\begin{align*} S_b&=\text{Mach }3.2 \end{align*}$

Step 1

1 of 3Given the Mach number, find the cone angle. Note that the Mach number is the ratio of the speed of an object to the speed of sound in the surrounding medium.

$M=\dfrac{S_a}{S_s}$
