A 2.00 kg piece of clay traveling to the right at 7.00 m/s collides and sticks to a horizontal rod pivoted at point A. The rod is initially stationary but it is free to rotate without friction about a perpendicular axis going through point A. The rod has a mass of 8.00 kg and a length of 1.00 m and it is on a sheet of frictionless ice. The top view is shown in the diagram below. 90 How much mechanical energy was converted into other forms of energy?
