The mechanical system shown in Figure 4_23 is initially at rest. Att 0, a unit-step dis- placement input is applied to point A. Assume that the system remains linear through- out the response period. The displacement x is measured from the equilibrium position. If m = 1 kg, b = 10 N-s/m, and k = 50 N/m, find the response x(() as well as the values of x(0+), 2(0+), and x(00).
