Homework Help: physics

Posted by sharkman on Wednesday, October 31, 2012 at 7:48pm.

A thin non-uniform rod of length L=2.00 m and mass M=9.00 kg is free to pivot about an axis at one end. The CM of the rod is at a distance d=1.30 m from that end as illustrated below. The rod's moment of inertia about an axis through its CM and parallel to the rotation axis is ICM=2.57 kg m2.

The rod is released at rest from an angle θ=33.0. Calculate the speed of the center of mass when the rod is horizontal.
