A moving point disturbance travels at a supersonic speed. It creates two spheres one at time (t) and the next one after (8t) time interval, 36 m ahead. Assuming the medium to be standard sea level atmosphere with 20°C, calculate the Mach number and velocity of the object and the Mach angle of the cone created by the disturbance.

5. Typical cruising speeds and altitudes for three commercial aircraft are: Dash 8: Cruising speed: 500 km/h at an altitude of 4570 m. Boeing 747: Cruising speed: 978 km/h at an altitude of 9150 m. Concorde: Cruising speed: 2340 km/h at an altitude of 16 600 m. Find the Mach number of these three aircraft when flying at these cruise conditions. Use the properties of the standard atmosphere discussed in the previous problem.
