To keep the calculations fairly simple, but still reasonable, we shall model a human leg that is 92.0 cm long (measured from the hip joint) by assuming that the upper leg and the lower leg (which includes the foot) have equal lengths and that each of them is uniform. for a 70.0 kg person, the mass of the upper leg would be 8.35 kg , while that of the lower leg (including the foot) is 5.50 kg . take that x-axis is directed horizontally and the y-axis is directed vertically downward.

a. find the x-coordinate of the center of mass of this leg, relative to the hip joint, if it is stretched out horizontally.

xc= cm
