Problem

Three point masses are arranged in the

xy

-plane:

0.30\,\text{kg}

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

, another

0.30\,\text{kg}

(-0.20\,\text{m},0)

, and

0.40\,\text{kg}

(0,0.30\,\text{m})

. Could any axis parallel to the

z

-axis yield a rotational inertia of

0.040\,\text{kg}\,\text{m}^2

for this system? Briefly justify your numerical conclusion.
