How Does Gravity Influence Spring Potential Energy in Physics?

[NickStar]

Homework Statement

The weight is falling from a height of 1 meter. Then it touches a spring and it contracts. The weight of a body is 2 kg and k of the spring is 100 N/m.
1) What's the maximum contraction of the spring
The answer is supposed to be 0.852m(I got 0.392m)

Relevant Equations

E=1/2kx2

Your writing is not clear enough to be posting as images. Forum rules request you only use images for book extracts and diagrams.
Did you take into account that gravity does not stop acting when the mass hits the spring?
You do not need to find the impact speed. Just work with energy, end to end.

Thank you, I didn't put gravity to my equation. After I did, I got the right result.
