Answer:
Explanation:
4.95s≈5s
Use equation :
h=G*t²/2
h=120m ----hight of cliff
G=9.81m/s²
t=?
-----------------------
h=G*t²/2
120m=9.81m/s²*t²/2
240m=9.81m/s²*t²
t²=240m/ 9.81m/s²
t²=24.46s
t=√24.46s²
t=4.95 s≈5s

1) Make sure the service portion of the structure stays above the highest probable water level.
2) Make sure the support structure in contact with the water can withstand the tidal flows
3) Consider whether the added restriction of the proposed structure will altar the height of, or water velocity contained in, the tidal exchanges.
4) Consider whether a dock needs to have mechanisms to compensate for large sea level changes.
