Explanation :

Pls refer to the attachment for the complete detailed solution .

Things used to solve :-

1) The three equations of motion.

=> v = u + at

=> v² = u² + 2as

=> s = ut +1/2at²

2) The method of solving quadratic formula by quadratic formula method.

i.e

x = -b±√b²-4ac/2a

3) We have assume h^½ = y. So , that we can get a quadratic equation , which we solved to get the value of h.
