Consider the base excitation system of a mass of 14 kg, 14* + 2x = 2y where y = 2.5 sin(0.32t). To reduce the vibration of the mass, an absorber system, (ma, ka), tuned to the natural frequency of the system is added. Let the ma = 0.75 kg. It is true that (approximate to the 3rd digit after decimal point) The amplitude of vibration of the absorber mass is 29.902 The amplitude of vibration of the primary mass is 3.387 The amplitude of vibration of the absorber mass is 11.961 The amplitude of vibration of the primary mass is 16.937 None of the answers is correct
