Her arms are initially straight out from her body, then she tucks them into herself, changing her rotating speed. She is 60 kg, with her arms being 7 kg altogether. a) Using the diagrams (in the video), (assuming the swing itself is negligible), use only variables to equate the initial and final states of angular momentum. {{youtube>bKkVkdZPH2g?large}} ---- Part 2: b) Using the equation created in part A, what is the final angular velocity of the woman? Her torso's radius is .2 m and her arms are 1.7 m long. {{youtube>OHynWTJrJ5s?large}} === Four Quadrants === {{183_notes:examples:angular_momentum_quadrant.png}} 183_notes/examples/videoswk13.txt Last modified: 2016/08/19 01:40by waterso8
