Mechanical vibrations

    I don't understand how to go about solving a problem like this;

    A weight stretches a spring 3 inches. It is set in motion at a point 4 inches below it's equilibrium point with zero velocity.

    -Find the maximum amplitude
    -When does it reach (the first time) it's highest point
    -Find it's maximum velocity

    Your governing equation will be
    [tex]m\ddot{y} + ky = 0[/tex]
    which is a simple harmonic motion

    This will allowed you to compute k/m.

    This is the initial condition which will allowed you to determined the arbitrary constants when solving the governing equation.
