Q2:- An accelerometer having an un-damping frequency of B0 Hz and a damping constant of c = B N . s /m is attached to a vibrating structure. When the structure vibrates with an acceleration amplitude of 7'5 m/ s2 and a frequency of 50 Hz, the instrument records the acceleration amplitude as B m/ s2 . Determine the suspended mass m and the spring constant k of the acceleromete
