What is the resulting period of the oscillation?

Homework Statement

A 0.16-kg mass is hanging from a spring with spring constant 14 N/m. Then the mass is displaced from the equilibrium by 2.9 cm and let go.

Homework Equations

the period is the time for a one full cycle so the equation would be T= 2∏sqrtm/k

The Attempt at a Solution

here's what I did I 2∏sqrt0.029m/14N/m

T=0.286s

I felt like that was to simple to solve especially in physics, what is the proper way of solving this equation?

The same error as in the other problem you posted. 'm' is the mass, not the displacement.
