2. A spring-mass system, with m = 100 kg and k = 400 N/m, is subjected to a harmonic force f(t) = Fo cos wt with Fo = 10 N. Find the response of the system when w is equal to (a) 2 rad/s, (b) 0.2 rad/s, and (c) 20 rad/s. Discuss the results. [ Solution: (a) x = 0, (b) = 0.025 cos(0.2t), (c) = -0.00025 cos(20t) ]
