The spring constant can be determined from the oscillatory motion. For this case, Newton's second law gives

[(m(d^2)x) / (d(t^2))] + kx = 0

where x is the displacement from the equilibrium position. The sample mass is suspended from the spring by a sample holder.

Does m in this formula include the mass of the sample holder?

A. No

B. Yes

C. None of the above
