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?

Step 1

Given: time, t = 4 s

Angle = 25^{o}

Speed of sound, v = 325 m/s

Find: How fast is the plane travelling?

what is the altitude of the plane?

Step 2

Speed of the plane can be calculated by Match cone angle relation:

v_{sound} = speed of sound

v_{airplane} = speed of airplane

Step 3

Altitude of the plane is given by:

where, h = height of the airplane
