1. The problem statement, all variables and given/known data A solid wood door of width 1.00 m and height 2.00 m is hinged along one side and has a total mass of 49.0 kg. Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.500 kg, traveling perpendicular to the door at 14.0 m/s just before impact. Find the final angular speed of the door with the mud stuck to it. I'm totally lost on this one. Four different approaches, four very different answers, all of them wrong. Please help.
