The policy here is that you have to show your attempt at a solution. How does Humpty-Dumpty move? with constant velocity? Or does he accelerate?

It seems like a case of free-fall.
u=0,a=g and t is given
Use the equation H=ut+1/2at2
But this is what I presume.There isn't any clear information about the motion of Humpty Dumpty.

Thanks, I got it.
I used H=ut+1/2at2
but it seemed I was inputting the wrong digit to the calculator
