0.40\,\text{kg}

uniform rod

0.60\,\text{m}

long rotates about an axis perpendicular to the rod through one end. Two small spheres, each of mass

0.20\,\text{kg}

, are attached to the rod at distances

0.15\,\text{m}

and

0.60\,\text{m}

from the axis, respectively. Determine the rotational inertia of the entire assembly about the axis. Give your result to two significant figures.
