0.50\,\text{kg}

mass is located at the point

(0.30\,\text{m},\;0.40\,\text{m})

in the

xy

-plane. Calculate its rotational inertia about an axis that passes through the origin and lies along the line

y = x

. (a)

3.5\times10^{-3}\,\text{kg}\cdot\text{m}^{2}

(b)

2.5\times10^{-3}\,\text{kg}\cdot\text{m}^{2}

(c)

5.0\times10^{-3}\,\text{kg}\cdot\text{m}^{2}

(d)

1.3\times10^{-3}\,\text{kg}\cdot\text{m}^{2}
