You look directly overh
j nyky+g/ 7as h*b4t1uead and see a plane exactly 1.5 km above the ground flying faster than the speed of sound. By the time you hear the sonic boom, the plane has traveled a horizontal distance of
a+g/4n b*u1 ysjtyhk 7 2.0 km. See Fig. 12–34. Determine
(a) the angle of the shock cone, $\theta$
$^{\circ} $
(b) the speed of the plane (the Mach number). Assume the speed of sound is 330 m/s
