Extracted text: a. The accelerometer shown in Figure 3 has an undamped natural frequency of 110 Hz. The damping coefficient c of the accelerometer is 12.5 kg/s. The accelerometer is used to measure the vibrations emanating from the floor of a processing plant. When the accelerometer is rigidly fixed unto the vibrating floor it records an amplitude of 9 m/s? occurring at a harmonic frequency of 70 Hz. If it is known that the true amplitude of the floor's vibration is 8.5 m/s?, calculate the mass (in kg) and the stiffness (in N/m) of the accelerometer. Seismic mass Floor vibrations
