Question

The route the Concorde took is displayed below The diameter in kilometers of the circular region in which people on the ground hear the Concorde's sonic boom directly, not reflected from a layer in the atmo sphere, is a function where h, the Concorde's altitude in kilometres, T, air temperature at ground level in degrees Kelvin, where degrees Kelvin is equal to degrees Celsius plus 273.15, and rauredhr deagies Kelvin per kilometre (a) Over the interval [50, 300 kilometres for D and (0,5 degrees Kelvin per kilometre for Ti, with an air temperature on the ground of 30 deg degrees Celsius, plot the level curves (contour plot) in the (D, Ta) plane when the plane is at height h 5, 10, 15, 20 kilometres (b) Assume that the Concorde passes through the sonic barrier at an altitude of 16.8 km, with a vertical temperature gradient of 5 Kelvin per kilometer. How far due north of the French coastline must the Concorde fly to ensure
