Mach Angle Example Problem

Use the Mach Cone to find speed of the aircraft, and time until a ground observer will hear it after it flies overhead. This Mach Angle Example Problem demonstrates how to find the speed of sound in air, how to find the Mach Angle, the velocity of the aircraft, the time until the sound reaches the ground after the plane passes overhead, and where the plane was when it emitted the sound that is first heard at the ground.
