Homework Help: Angular Momentum Problem of turntable

  1. Oct 8, 2006 #1
    This seems pretty basic but I am drawing a blank. Thanks in advance.

    "A cat is sitting on the rim of a wooden turntable that is free to turn about a vertical axis. The turntable's mass is 3 times the cat's mass and is initially at rest. The cat then starts walking around the rim at a speed of 0.6m/s relative to the ground. How fast does the turntable's rim move relative to the ground?"

    conservation of angular momentum. Just like linear momentum, when two things push apart, mv of one object equals -mv of the other, in angular momentum, the Iw of one equals the -Iw of the other.
