I have an object number 1 (M1) and second object number 2 (M2).(adsbygoogle = window.adsbygoogle || []).push({});

Mass of number 1 is known and number 2 is unknown.

And M1 << M2. Both massess are attached to a spring with spring constant k, where k is known. Also the period T is known. How do I solve mass number 2?

The system:

---<spring>---

M1-|||||||-M2

No gravitation, mass of the spring is negligible and so is friction in the system.
