**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 don't even know where to start on this or what formulae to use... I only need assistance with calculating point E)
