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
