Arescue plane flies horizontally at a constant speed searching for a disabled boat. when the plane is directly above the boat, the boat's crew blows a loud horn. by the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-third its altitude above the ocean. (a) if it takes the sound 1.92 s to reach the plane, determine the speed of the plane. (take the speed of sound to be 343 m/s.) /s (b) what is its altitude?
