Problem

Four point masses are located at the corners of a square of side

2.0\,\text{m}

in the

xy

-plane:

3\,\text{kg}

(0,0)

2\,\text{kg}

(2,0)

4\,\text{kg}

(2,2)

, and

1\,\text{kg}

(0,2)

. The

1\,\text{kg}

mass is removed while the other three masses remain fixed. What are the coordinates of the new center of mass of the system? (a)

(1.20\,\text{m},\,1.00\,\text{m})

(b)

(1.33\,\text{m},\,0.67\,\text{m})

(c)

(1.33\,\text{m},\,0.89\,\text{m})

(d)

(1.33\,\text{m},\,1.11\,\text{m})
