You look directly overhead and see a plane exactly 1.5 km above the
wt8p ulw,shz:q7b*2 e e7hb l6 ground flying faster than the speed of sound.
:l 7lshb,utz 2b*wpehweq8 76By the time you hear the sonic 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
