Problem

A solid disk of mass

4.0\,\text{kg}

and radius

0.20\,\text{m}

is to be spun about an axis parallel to and on the same side of the disk’s central axis. If the required rotational inertia about this new axis is

0.12\,\text{kg}\cdot\text{m}^2

, what should be the distance

d

between the two axes? (a)

0.14\,\text{m}

(b)

0.01\,\text{m}

(c)

0.10\,\text{m}

(d)

0.20\,\text{m}
