## Homework Statement

The position of a 49 g oscillating mass is given by x(t)=(1.8cm)cos12t, where t is in seconds.

## Homework Equations

k=mg/x

## The Attempt at a Solution

I've tried working this problem multiple different ways and it is just not working for me.

I used k= (.049*9.8)/.018

Is this correct with the information I've been given? I used up all my attempts and the solution is apparently

7.1 N/m...but I keep coming up with roughly 26.7 N/m
