A 6-meter long rigid rod with a mass of 2 kg has small weights attached to its ends. The system is attached to a frictionless axle that passes through the rod 2 meters from the left end, as shown in the figure. When released from rest in a horizontal orientation, the system begins to rotate. What is its angular acceleration?​
