The flexible footbridge shown spans shark infested waters. Humans are expected to walk across the bridge and shake it with a harmonic force of 250 N at a rate of 2 Hz. A tuned vibration absorber is hung from the bridge to mitigate steady-state vibrations of the bridge. The spring stiffness is ka is 1000 N/m. What value is needed for the absorber mass ma? ka ma DAL
