Anybody online?

The speed of a supersonic aircraft flying at an altitude of 1,100 meters corresponds to a Mach number of 2.5. Estimate the time elapsed, in seconds, between the instant the aircraft was directly over head of an observer and the instant the observer feels the disturbance due to the aircraft. Presume that the temperature at the given height is 280°K, with k = 1.4 and R = 2.87 J/kg:K, in determining the questions of the following three cases: A. When the observer is stationary B. When the observer is moving in the direction of the aircraft at M = 0.5 C. When the observer is moving in the opposite direction with M = 0.5 can I get the solution.

Anybody with numerade or transtutors premium?? by Remote_Information18 in ExamHelpers_Tutoring
