A supersonic aircraft flies at an altitude of 3000 m. An observer on the ground hears noise generated by the aircraft, which is 3000 m away horizontally, after 12 s. assume that the atmosphere is isothermal. Determine: (a) The Mach number of the aircraft. (b) The velocity of aircraft. (c) The distance traveled before the observer hears the noise, and (d) The temperature of the isothermal atmosphere.

I need the answer as soon as possible

I need help on 3a

Stagnation pressure and temperature probes are located on the nose of a supersonic aircraft. At 35,000 ft altitude a normal shock stands in front of the probes. The temperature probe indicates T0 = 420F behind the shock. Calculate the Mach number and air speed of the plane. Find the static and stagnation pressures behind the shock. Show the process and the static and stagnation state points on a Ts diagram.
