Q2. An electronic device (m₁ = 4 kg) sits inside a timber box (m2 = 4 kg) through two springs with stiffness 2000 N/m. The stiffness of the two springs between the box and the ceiling is 1000 N/m. Assume the displacements of the device and the box are denoted by x1 and x2, respectively. (1) Find the total kinetic energy and potential energy of the system (2) Use Lagrange equation method to derive its equations of motion. (3) Determine its natural frequencies. (4) Find out its associated vibration modes. 1000 N/m 1000 N/m 2000 N/m 4 kg >2000 N/m 4 kg
