6.3 Figure P6.3 shows a mass-damper system (no stiffness, Problem 2.3). Displacement x is measured from an equilibrium position where the damper is at the "neutral" position. The external force fa(t) is a short-duration pulse function: fa) 5N for 0 s i s 0.02 s, and fat)-0 for> 0.02s. The system parameters are mass m-0.5 kg and viscous friction coefficient b-3N-s/m and the system is initially at rest. Use Simulink to determine the system response and plot displacement x(t) and velocity x(t) Figure P6.3 6.3 Figure P6.3 shows a mass-damper system (no stiffness, Problem 2.3).
