Homework Statement
An object falls from height h from rest. If it travels .5h in the last second before hitting the ground, determine how long it takes to fall and the height h.
xi = .5hm, t =1s, a = 9.8m/s^2, xf = 0m,
Homework Equations
Vf = Vi + at
xf = xi + .5at^2
The Attempt at a Solution
xf = xi + .5at^2
0 = .5h + .5(-9.8)(1)
h = 9.8m
I know that this answer is not correct, I am having trouble figuring out how to manipulate the given data into one of those equations to either come up with h or find the total time.
