Cliff height. You are climbing in the high Sierra where you suddenly find yourself at the edge of a fog-shrouded cliff. To find the height of this cliff, you drop a rock from the top and 10 s later hear the sound of it hitting the ground at the foot of the cliff. Ignoring air resistance, how high is the cliff if the speed of the sound is 330 m/s?

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. 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.
