A 147g ball is dropped from a height of 56.5cm above a spring of neglibible mass. The ball compresses the spring to a maximum displacement of 4.45393cm. The acceleration is 9.8m/s^2. calculate the spring force constant k. Answer in units of N/m.

2. Relevant equations

Not sure

3. The attempt at a solution

I converted the mass from 147g to .147kg the height from 56.5cm to .565m and the displacement from 4.45393cm to .0445393m.

Now im stuck and don't know what to do

I tried mgh=.5kx^2 but didnt work
