U = 1/2 * k * x²
U = 0.003J
x = 0.0055m
k spring constant
Well, wind can change landforms by storms, and hurricains, or other things that contain air...
~~~~~~~~~~~~~
Like, over a period of time... Wind can make landforms decrease in size, by weathering.

I'm just guessing I'll be honest I don't know
Answer:
18 m
Explanation:
y = 10x − 5/9 x²
When the projectile lands, y=0:
0 = 10x − 5/9 x²
0 = x (10 − 5/9 x)
x = 0, 18
The range of the projectile is 18 m.
