Hi, I got this question wrong on a test and am really quite lost about it. I'd appreciate somebody running me through it. --- "Suppose a 55 kg person stands at the edge of a 6.5 m diameter merry go round turntable that is mounted on a frictionless bearing and has a moment of inertia of 1700 kg m^2. The turntable is at rest initially, but when the person begins running at a speed of 3.8 m/s (with respect to the turntable) around its edge, the turntable begins to rotate in the opposite direction. Caculate the angular velocity of the table." --- So I set up conservation of angular momentum L_f = L_i and (Iw)_f = (Iw)_i Can somebody please help me from there?
