doofy Spring constant problem problem

[Supaiku]

A toy make requires a spring mechanism to drive an attached component with a period of .50s. If the mass is 10g what must thevalue of hte psring constant k be?

I can't figure out how the heckle you are supposed to solve for this without the distance. Is it me or the question, if it's me; how bout' some equations.

You don't require anything else to solve the problem.

The time period is just

T = 2 \pi \sqrt{\frac{m}{k}}

Thanks! but uh... where's that from? I can't figure it out :(

EDIT: nvm, Thanks again:D

The equation for Simple harmonic motion (derived from the equation F= -kx ) is

x=Asin\omega t

where

\omega = \sqrt\frac{k}{m}

From this, the time period of motion is \frac{2\pi}{\omega}

So, you can derive that formula.
