Experimental aircraft for the military are to be ranked relative to their Mach number, Ma. Mach number is a ratio of the velocity, V, of the aircraft to the speed of sound, c. The speed of sound, however, is a function of temperature. The theoretical equations for the speed of sound can be expressed as c = (kRT)^0.5, where,
k = specific heat ratio that varies with temperature but has no dimension. However, for this problem assume that it is a constant with a value of 1.4.
R = Gas constant for air (53.33 ft ?lbf/lbm ? °R)
T = Temperature, °R
