b. (1.117 m, 0.767 m)

c. (0.767 m, 0.767 m)

d. (1.117 m, 1.117 m)

Final answer:

The center of mass of three symmetrically arranged identical meter sticks would be at the geometric center of the equilateral triangle they form. Upon calculation, the center of mass would be at approximately (0.5 m, 0.289 m), which does not match any of the provided options.

Step-by-step explanation:

To calculate the location of the center of mass of three identical uniform meter sticks placed on the floor, we'll assume they are positioned in such a way that they are symmetric around a central point. With each meter stick having an equal mass and uniform distribution, their individual centers of mass are at the 0.5 m mark (halfway along their lengths).

Since the meter sticks are identical and arranged symmetrically, they form an equilateral triangle with each other. This implies that their collective center of mass will be at the center of this equilateral triangle.

If we assume one corner of the equilateral triangle to be at the origin of our coordinate system (0,0), the other two corners will be at (1,0) and (0.5, √3/2), since the height of an equilateral triangle is √3/2 times the length of one side. The x-position of the center of mass will be the average of the x-coordinates of the corners, and the y-position will be the average of the y-coordinates.

x-position of center of mass = (0+1+0.5)/3 = 0.5 m
y-position of center of mass = (0+0+√3/2)/3 = √3/6 m ≈ 0.289 m

However, since none of the provided options in the question match the calculated values, I would advise the student to check the premise of the question, or whether there was an error in the arrangement of the meter sticks specified in the question.
