(5) (20 pts.) Consider a mass-spring-dashpot system with m = 1 (kg) and k = 26 (N/m). Assume also that the dashpot pro- vides c (N) of resistance for each (m/s) of velocity. Determine the value of c for which the motion is critically damped. Now assume that the external force F(t) = Fo cos wt (N) is applied. Find the minimal value Cmax of the damping constant c for which a practical resonance may not occur. Also find the value of w that would induce practical resonance if c=Cmax
