Find the values of \(k_{2}\) and \(m_{2}\) in Problem 9.54 in order to have the natural frequencies of the system at least 30 percent away from the forcing frequency.

Data From Problem 9.54:-

An electronic instrument of mass \(20 \mathrm{~kg}\) is to be isolated from engine vibrations with frequencies ranging from \(1000 \mathrm{rpm}\) to \(3000 \mathrm{rpm}\). Find the stiffness of the undamped isolator to be used to achieve a 90 percent isolation.
