Question

you hear a sonic boom of a high speed jet plane exactly 3.50s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 24.0 degrees. a) how fast is the plane traveling? b) what is the alititude of the plane?

Answer 1

Here is what I solved before, please modify the figures as per your question. Please let me know if you have further questions. Ifthis helps then kindly rate 5-stars.

you hear a sonic boom of a high speed jet plane exactly 2.90 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 20 degrees above the horizon. assume 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?   

v (plane ) = v of sound/sin? =325 /sin 27. = 716 m/s
