Homework Statement:

A 1.6 kg mass attached to a spring undergoes simple harmonic motion of amplitude 0.12 m and has an energy of 72 J

Relevant Equations:

E=(1/2)(k)(x^2)+(1/2)(m)(v^2)
T=2pi sqrt{m/k}
Im not sure how to find k if I'm not given a force or period.

Is there some position of the mass where you know both x and v?
