A football is placed on a line 25m from the goal post. The kicker kicks the ball directly toward the post, giving the ball an initial velocity of 21.0m/s [47deg above the horizontal]. The horizontal bar of the goal post is 3.0 m above the field. How far above or below the bar will the ball travel?

this is the problem and what i've got so far is breaking initial velocity into two components; vertical and horizontal.
Vix = 14.32 m/s [up] Viy = 15.46 m/s [forward]

what should i do next?
 
use the forward v and the d to goal to calculate the time to goal
v=d/t
then use the t in
y = vi*t + 1/2*g*t^2 ( remember g is down so -9.81)
finally compare y to 3.0 to get over/under
