Find the response of the spring-mass system shown in Fig. 6.6 (a) for \(k_{1}=k, k_{2}=2 k\), \(k_{3}=3 k, m_{1}=m, m_{2}=2 m\), and \(m_{3}=3 m\) with \(k=10^{4} \mathrm{~N} / \mathrm{m}\) and \(m=2 \mathrm{~kg}\) when a force, in the form of a rectangular pulse of magnitude \(1000 \mathrm{~N}\) and duration \(0.25 \mathrm{~s}\), is applied to mass \(m_{1}\) in the direction of \(x_{1}\).
