Circular relationship, err, function for a circle. X^2 + Y^2 = R^2

Radius of ball -- 20"
length of overpass -- 32", believedly.

16^2 + y^2 = 20^2
y = 12. 12 is the height from the center of the sphere to the overpass.

20 - 12 = 8" the ball dips down at maximum, giving us only 2" of impact room to play with.
