As shown in the figure, a homogeneous rod with a length L = 1 (m) and mass m = 0.4 (kg) is fixed so that it can rotate in the middle. Two springs with constant k = 15 (N/m) are connected at both ends of the rod. The other ends of the springs are fixed and the springs are unstretched. The rod is rotated as 0 «from its equilibrium position and released. What is the angular frequency of the rod in (rad/s)? g = 10 (m/s²)
