There is a special place in Hell for physics students who drop stones in wells. Wells don't need stones dropped in them, or the water level below bottom will decrease.
Let t be the time of dropping the first stone.
disance apart= distance firstdistance2nd
= 1/2 g t^2  1/2 g(t1)^2
so, at t=2
= 1/2 g 4  1/2 g 1
