Step-by-step explanation:
Let the mass of the person be [tex]m[/tex].
Let the spring constant be [tex]k[/tex].
Let the displacement in spring be [tex]x[/tex]
Let the acceleration due to gravity be [tex]g[/tex]
As it is given that the person just stands,the forces are balanced.
So,[tex]mg=kx[/tex]
Given,
[tex]m=60Kg\\k=2500Nm^{-1}\\g=9.8ms^{-2}[/tex]
[tex]60\times 9.8=2500\times x\\x=\frac{588}{2500}=0.2352m[/tex]
