Question 4
In a mass-spring system where mass m = 1 kg, spring constant k = 2, and damping c = 0,
the position of the mass x(t) can be modelled by the differential equation below:
x" + 4x = F(t)
F(t) is the external force applied to the mass and F(t) = {01
if-1<t≤0
if 0<t<1
(a) Compute and plot the Fourier series of F(t) to verify your answer.
(b)
Hence find and sketch the steady period solution of x(t).
