assume g = 32ft/s^2

A golf ball is hit at ground level. the ball is observed to reach its maximum height above ground level 8.3 s after being hit. 1.2 s after reaching this maximum height, the ball is observed to barely clear a fence that is 482 ft from where it was hit. How high is the fence? answer in units of ft.

i think the problem I'm having with this problem is figuring out the height of the fence, i know how to figure out the max height, but where do i go from that. i know all the formulas for kinematics in 2 dimensions. i would appreciate any help u can give me.

thanks
