3. The attempt at a solution

So I first tried by saying consider a time t in which mass m is directly above the origin O. I.e., mass m at the Cartesian coordinate (0, 4l/3). I wrote a = a(t) as the extension function of the spring, which has 0 natural length. So, I applied the cosine rule and found:

But then how do I find the coordinate of the 4m mass?

Then I'll need some help in going about some other parts of the question, but first need help with finding the coordinate of 4m...

Thanks
