1. A T-shaped assembly is made of two identical uniform bars of length d and mass m each. One end of one of the bars is rigidly connected to the midpoint of the other. The assembly is pivoted at the connection point and held in position A. After it is released, the assembly swings down in the vertical plane. Neglect all resistive forces.
Find the instantaneous linear speed of the bottom point of the assembly as it passes through position B
2. I tryed to use energy equation to find the velocity, but moment of inertia is unknown
[itex]2mg(d/2)=1/2(2m)v_{cm}^2+1/2I_{cm}\omega^2[/itex] so I can't figure out how to continue
