A 72 kg and 180-cm tall person lies on a light (massless) board which is supported by two scales A and B. Scale A is under the top of her head and scale B is at the bottom of her feet. If the center of mass of the person is located 100 cm from the bottom of her feet (or 80 cm from the top of her head). What will be the scale reading on scale A?

The meterstick shown is 100 cm long. It is free to pivot around its center of gravity (CG), which is at the 50 cm mark. There is a 24.0 N block hanging from the 80 cm mark. Decide where each of the other blocks should be placed, one at a time, to balance out the 24.0 N block. At what mark on the meter stick would you place a 19.0 N block to balance the 24.0 N block? mark: At what mark on the meter stick would you place a 44.0 N block to balance the 24.0 N block? mark:
A person is standing on a level floor. His head, upper torso, arms, and hands together weigh 438 N and have a center of gravity that is 1.30 m above the floor. His upper legs weigh 144 N and have a center of gravity that is 0.730 m above the floor. Finally, his lower legs and feet together weigh 87 N and have a center of gravity that is 0.240 m above the floor. Relative to the floor, find the location of the center of gravity for his entire body. m above the floor

In exercise physiology studies, it is sometimes important to determine the location of a person's center of mass. This determination can be done with the arrangement shown in the figure below. A light plank rests on two scales, which read F, = 395 N and F, gi = 340 N. A distance of 1.65 m separates the scales. How far from the woman's feet is her center of mass? g2 1.65 m F 18. F 82
