JahnaviDholakia: But the velocity is not the displacement. You have them mixed up.

JahnaviDholakia: I feel it has something to do with the kinematical equations using the height and the acceleration due to gravity.

JahnaviDholakia: Never mind, I am just too sleepy I read it wrong

alfredmelwin25p5fmxx: then, use the k. e s=1/2at^2

alfredmelwin25p5fmxx: that initial velocity of the stone in case 1 is 15 m/s.
