(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The graph of displacement vs. time for a small mass at the end of a spring is shown in the figure. At t = 0, x = 0.43 cm. If m = 16.9 gram, find the spring constant, k.

T = 0.69 seconds

2. Relevant equations

F = kx

3. The attempt at a solution

mg=kx

(.0169 kg)(9.8 m/s^2) / (.0043m) = 38.56

Which is wrong. Is there another way to solve this problem that i'm not seeing?
