Suppose I drop a rock off a cliff at height h. As it falls, I snap a million photographs at random intervals. On each picture I measure the distance the rock has fallen. Ignoring air resistance:(adsbygoogle = window.adsbygoogle || []).push({});

x(t) = 1/2 g t^2

v(t) = g t

total flight time = T = Sqrt[ 2 h/g]

My confusion is that in this statement: "The probablity that the camera flashes in the interval dt is dt/T" I don't see how or why this statement is true.
