A uniform rod ( L = 3.0 meter) and mass (M = 1.0 kilogram) is pivoted about a horizontal frictionless pin through one end. The rod is released from rest at an angle of 30 degree below the horizontal. Determine what is the angular speed of the rod when it passes through the vertical position? (The moment of inertia of the rod about the pin is 3.0 kg .m2). (g = 9.8 m/s2).
