Plotting a graph of accelleration agains displacement (x)

    Plotting a graph of acceleration agains displacement (x)

    A mass of 0.3kg suspended from a spring of stiffness 200Nm-1. If the mass is displaced by 10mm from its equilibrium position and released calculate:

    A) frequency of vibration

    B) max velocity

    C) max acceleration

    D) mass required to produce double the maximum velocity but using the same amplitude

    E) plot a graph of acceleration against displacement (x) (for values of x from x= -10mm to x= 10mm


    A) f=1/2∏*√k/m

    B) Vmax=A*ω

    C) a=A*ω^2

    D) i doubled Vmax then used ω=Vmax/A
    Then m=k/ω^2

    E) i have no idea

    I am not after the answers as such but just a nudge in the right direction, i dont even know where to start on this or what formulae to use... I only need assistance with calculating point E)
