If you are at the surface of the earth the acceleration is g = 32.2 feet/sec 2 or 9.8 meter/sec 2.Integrating the acceleration once gives V = V o + g T where V o is the initial velocity, presumably zero, and T is the time of fall. Integrating once more gives d = V o T + gT 2 /2. So taking V o = 0 you get T = sqrt(2d/g) … small batch cookies oatmeal
