Using MATLAB, solve Problem 5.90. Use the MATLAB function stepfun for the rectangular pulse.

Data From Problem 5.90:-

Find the response of the system shown in Fig. 5.5

(a) using a numerical procedure when \(k_{1}=k, k_{2}=2 k, k_{3}=k, m_{1}=2 m, m_{2}=m, F_{2}(t)=0\), and \(F_{1}(t)\) is a rectangular pulse of magnitude \(500 \mathrm{~N}\) and duration \(0.5 \mathrm{~s}\). Assume \(m=10 \mathrm{~kg}, c_{1}=c_{2}=c_{3}=0\), and \(k=2000 \mathrm{~N} / \mathrm{m}\), and zero initial conditions.
