Aperson's center of mass is easily found by having the person lie on a reaction board. a horizontal, 3.0-m-long, 6.1kg reaction board is supported only at the ends, with one end resting on a scale and the other on a pivot. a 57kg woman lies on the reaction board with her feet over the pivot. the scale reads 22kg. assume that the woman doesn't move and a position of her center of mass doesn't change. what is the distance from the woman's feet to her center of mass?
