You look directly overhead and see a plane exactly 1.5 km a
o3ldzxwe6 xp355x s9ubove the ground flying faster than the speed of sound. By the time you hear the
55x u3lpx6zw ed93o sxsonic boom, the plane has traveled a horizontal distance of 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
