6. A rescue 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 perceives the horn’s
sound, the plane has traveled a distance equal to half its altitude
above the ocean. If it takes the sound 2.00 s to reach
the plane, determine (a) the speed of the plane and (b) its
altitude. Take the speed of sound to be 343 m/s.
does it arrive?
