A uniform thin rod of mass 2.0 kg and length 0.75 m is pushed from rest across a level frozen pond and moves without friction. It is free to both translate and rotate. A total of 25 J of work is done to the rod during the push. After the push, its final center of mass speed is 3.0 m/s. What is its final rotational speed around its center of mass? Please show work and explain!
