Doofy Spring constant problem problem

  1. Oct 25, 2004 #1
    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.

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

    [tex]x=Asin\omega t[/tex]

    where

    [tex]\omega = \sqrt\frac{k}{m}
    [/tex]
    From this, the time period of motion is [tex]\frac{2\pi}{\omega}[/tex]

    So, you can derive that formula.
