The human body's center of gravity can be determined using a device call a reaction board. In one such measurement, as shown in the figure below, a60 kg woman lies on a \( 2.5 \mathrm{~m} \) long. \( 6.0 \mathrm{~kg} \) reaction board with her feet over a fixed support at one end of the board. A scale under the other end reads \( 250 \mathrm{~N} \). What is the distance din meters, this is the distance from the woman's feet to her center of gravity? Hint: Make the oxis of rotation (pivot point) to be located along the unknown force.
