**Homework help. (Solved)**

*A golf ball is hit at ground level. The ball is observed to reach its maximum height above ground level 4.3s after being hit. 1.2s after reaching this maximum height, the ball is observed to barely clear a fence taht is 309 ft from where it was hit. The accelerration of gravity is 32 ft/s^2. How high is the fence? Answer in units of ft.*

The horizontal velocity is constant and 56.18 as defined as distance over time. The vertical velocity is variable but I found the instantaneous velocity (137.6) in an attempt to find the initial angle. I am stumped. I keep coming up with values around 200 ft and that doesn't seem possible.

[edit] Solution is 272.8 [/edit]
