Problem

Four point masses are placed on a frictionless horizontal table as follows: a

2\,\text{kg}

mass at

(-2\,\text{m},\,0)

, another

2\,\text{kg}

mass at

(2\,\text{m},\,0)

, a

3\,\text{kg}

mass at

(0,\,3\,\text{m})

, and a

1\,\text{kg}

mass at

(0,\,-3\,\text{m})

. What is the

y

-coordinate of the center of mass of the system? a)

1.50\ \text{m}

0.75\ \text{m}

0\ \text{m}

1.13\ \text{m}
