<h2>
Answer:0.2352
</h2>
Step-by-step explanation:
Let the mass of the person be
.
Let the spring constant be
.
Let the displacement in spring be 
Let the acceleration due to gravity be 
As it is given that the person just stands,the forces are balanced.
So,
Given,


For a 30-60-90 triangle
if the shorter leg (oposite 30 degrees) is x then the other leg is x√3 and the hyptonuse is 2x
so
hyptonuse=8
8=2x
4=x
longer leg is 4√3, yep
so shorter leg or height will be 4 units
