First figure out the time by using the equation (you know v and x):
[tex] v_{x} = \frac{x}{t} [/tex]
Then, use the following equation to figure out what y (height of the field house is):
[tex]y= v_{y} t+ \frac{1}{2}at^{2} [/tex]
Remember that you can always analyze half of the scenario by dividing the time in half, and setting vy = 0 if at all it helps.
