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.
X - Xo = Vot + .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.
