Please show me formula, explain and what is the correct answer.

1) In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.

i) Find the magnification factor M for the frequency ratio r of 1.382.
