To determine the Mach speed of the aircraft, it is essential to use the concept of the sonic boom and the geometry of the situation. The process involves understanding the relationship between the speed of sound, the Mach number, and the distance at which the sonic boom is heard. Step-by-Step Solution Step 1: Define Known Quantities Altitude of the aircraft, h=5500 meters. Horizontal distance when the sonic boom is heard, d=9500 meters. Explanation: These quantities are directly given in the problem. The altitude is the vertical distance from the aircraft to the ground, and the horizontal distance is how far the aircraft has traveled horizontally when the sonic boom is heard. Step 2: Calculate the Slant Distance The slant distance s (the distance from the pe
