In exercise physiology studies it is sometimes important to determine the location of a person's center of mass. This can be done with the arrangement shown in the figure. A light plank rests on two scales, which give reading of Fg1 = 390 N and Fg2 = 310 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of mass?
