Calculate the speed of sound for the U.S. standard atmosphere using, c ? kRT where c represents the speed of sound in m/s, k is the specific heat ratio for air (k = 1.4), and R is the gas constant for the air (R = 286.9 J/kg·K) and T represents the temperature of the air in Kelvin. The speed of sound in atmosphere is the speed at which sound propagates through the air. You may use Excel to solve this problem.
