About what axis will a uniform, balsa-wood sphere have the same moment of inertia as does a thin-walled, hollow, lead sphere of the same mass and radius, with the axis along a diameter
Added by Jennifer M.
Step 1
Second, the moment of inertia of a thin-walled hollow sphere (like the lead sphere) about an axis through its center is given by the formula I = 2/3 * m * r^2. For the two spheres to have the same moment of inertia, we need to find an axis for the balsa-wood Show more…

A solid sphere and a hollow sphere made from different materials have the same mass and the same radius. Which of these two objects, if either, will have the greater rotational inertia about an axis through its center? Explain.
A sphere consists of a solid wooden ball of uniform density 800 $\mathrm{kg} / \mathrm{m}^{3}$ and radius 0.20 $\mathrm{m}$ and is covered with a thin coating of lead foil with area density 20 $\mathrm{kg} / \mathrm{m}^{2} .$ Calculate the moment of inertia of this sphere about an axis passing through its center.
