Spring force and the period of it's ocilation

[Robertoalva]

1.A mass is attached to a vertical spring, which then goes into oscillation.
At the high point of the oscillation, the spring is in the
original unstretched equilibrium position it had before the mass
was attached; the low point is 5.8 cm below this. Find the oscillation
period.

Homework Equations

sin(α+ or -β)
sqrt(k/m)= ω

The Attempt at a Solution

having the half of 5.8cm
2.9cm k = mg

Think about this

T = 2(pi)sqrt(m/k)

How do you find k?

(force) (distance) = k and force in this case is mg

These are enough clues.
