General solution: ( u(t) = A \cos(\omega_n t) + B \sin(\omega_n t) ) Apply (u(0)=0.05 \Rightarrow A = 0.05) (\dot u(t) = -A\omega_n \sin(\omega_n t) + B\omega_n \cos(\omega_n t)) (\dot u(0)=0.2 = B\omega_n \Rightarrow B = 0.2 / 6.3249 = 0.03162\ \text{m}) Thus [ u(t) = 0.05\cos(6.3249 t) + 0.03162\sin(6.3249 t)\ \text{m} ] Amplitude ( = \sqrt{0.05^2 + 0.03162^2} = 0.05916\ \text{m} ). (Phase angle (\phi = \tan^{-1}(B/A) = 32.3^\circ).)
