1. The problem statement, all variables and given/known data
If provided only the spring constant K and the mass of an object undergoing simple harmonic motion how do you find the amplitude?

2. Relevant equations
Angular Frequency = sqrt (k/m)
Period = 1/t

3. The attempt at a solution
Using the two equations above you can derive $$\omega$$ period, and frequency. This gives you $$\omega$$, period, frequency, mass and the spring constant. Is it possible to solve for the amplitude with these variables?

Amplitude is a function of the energy in the SHM system and we don't have any information about that.

TotalEnergy = 0.5*K*Amplitude²
