A golf ball is hit at ground level. The ball is
observed to reach its maximum height above
ground level 2.2 s after being hit. 1.3 s after
reaching this maximum height, the ball is
observed to barely clear a fence that is 780 ft
from where it was hit.
The acceleration of gravity is 32 ft/s

.
How high is the fence?
