One Dimensional Kinematics of Object

[dbzheir]

Homework Statement

An object is released from rest at a height h. It travels 0.31h during the first second of its descent. Determine the average velocity of the object during its entire descent.

Homework Equations

X - Xo = volt + .5at^2
v^2 = Vo^2 + 2a(X - Xo)
X - Xo = .5(Vo + V)t

The Attempt at a Solution

I basically have no idea where to start.
.31/1 = .31 m/s is the velocity in the first second, but that is not the initial velocity, which is 0.
h = .5(0+Vf)t = .5Vf*t, but I have no idea how one would get a numerical answer, which is what I need.

Perhaps try figuring out what the height actually is to begin with. How far does any object fall under the influence of gravity in 1 second? You are told that this distance is 31% of the total distance, so to what height was it raised? See if you can work from there.

I love you.
Sorry for being an idiot, that's what always gets me.
