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)
