Given data
*The given mass of the ball is m = 0.400 kg
*The given height is h = 3.00 m
*The given spring constant is k = 600.0 N/m
*The value for the acceleration due to the gravity is

The expression for the spring compresses at a distance is given by the conservation of energy as
![\begin{gathered} U_s=U_p \\ \text{mgh}=(1)/(2)kx^2 \\ x=\sqrt[]{(2mgh)/(k)} \end{gathered}](https://img.qammunity.org/2023/formulas/physics/high-school/uu0oqvc0r0hde1a43v7dbf1hekc6r9zy7a.png)
Substitute the values in the above expression as
![\begin{gathered} x=\sqrt[]{(2*0.400*9.8*3.00)/(600.0)} \\ =0.198\text{ m} \end{gathered}](https://img.qammunity.org/2023/formulas/physics/high-school/eo186huy1j726szn0qsnt1zj5zgl34p69f.png)
