You aren't going to get much just by looking at the equation. I'd recommend posting the question.

Here is the basic equation for freefall 1-D motion in the vertical direction.

$y = y_0 + v_0t - \frac{1}{2}gt^2$
where
y is the position at time t
y0 is the initial position
v0 is the initial velocity
g is the acceleration due to gravity
t is the time (assuming we start the clock when the object is at y0).

In this equation I made the assumption that +y is in the upward direction.
