A long, uniform rod of mass 20.00 kg is pivoted at its top end. It is lifted a small angle and let go. When it reaches the very bottom of its swing, it is moving with angular speed ?o , and it has collision with a block of mass 3.000 kg that was originally at rest on a frictionless surface. After the collision the rod is seen to continue spinning in the same direction at 17.66 rad/s. As a result...
