Pregnancy shift of com. The figure below gives a simplified view of the weight supported on each foot of someone with weight mg standing upright with half the weight supported by each foot. An x axis lies along the foot, with $x_f = 0$ at the forefoot and $x_h = 25$ cm at the heel. On each forefoot the downward force is $f(mg/2)$, where $f$ is the fraction of the weight on a foot that is supported by the forefoot. Similarly, on each heel the downward force is $h(mg/2)$. The foot (and the person) is in equilibrium around the center of mass. During pregnancy, the center of mass shifts toward the heels by 41 mm. What percent of the weight shifts toward the heels? (The center of mass shifts back to its initial position after pregnancy.)
