QUESTION2: Consider the disk in the Figure below connected to two springs. Use the energy method to calculate the system's natural frequency of oscillation for small angles \( \theta(t) \). (8 Marks) QUESTION 3: A mass of \( 1 \mathrm{Kg} \) is to be supported only on spring having stiffness \( 9800 \mathrm{~N} / \mathrm{m} \). Determine The damped frequency of the system \( \omega_{d} \). Find also the Logarithmic decrement and the amplitude after three Cyeles if the initial displacement is \( 0.3 \mathrm{~cm} \). (7 Marks)
