There is a special place in Hell for physics students who drop stones in wells. Wells dont 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 first-distance2nd

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

so, at t=2

= 1/2 g 4 - 1/2 g 1
