1. The problem statement, all variables and given/known data
Consider a 2.5kg mass oscillating at the end of a spring, with the frequency of 1.0Hz. The motion of the mass extends through 0.04m.

2. Relevant equations
Determine the spring constant-

3. The attempt at a solution

I can't find the right equation to set up this problem appropriately. The closest thing I could muster up was:

period=t= 2pi$$\sqrt{}$$m/k
1=2pi$$\sqrt{}$$(2.5/k)
(1/2pi)=$$\sqrt{}$$(2.5/k)
(0.1592)(0.1592)=2.5/k
0.02533=k2.5
=98.6971(n/m)

-I'll bet good money I applied that equation wrong.

That looks correct me.
