The solid disk has the greater moment of inertia.
Explicación
## Step 1The problem involves the concept of moment of inertia, which is a measure of an object's resistance to changes in its rotational motion. The moment of inertia depends on the mass of the object and the distribution of that mass around the axis of rotation.## Step 2In this problem, we have two objects: a solid sphere and a solid disk. Both objects have the same mass, but their shapes are different. The solid sphere has its mass evenly distributed around the axis of rotation, while the solid disk has its mass concentrated at the edge.## Step 3The moment of inertia for a solid sphere is given by the formula
, where
is the mass and
is the radius.## Step 4The moment of inertia for a solid disk is given by the formula
.## Step 5Comparing the two formulas, we can see that the moment of inertia for the solid disk is greater than that for the solid sphere, because the factor of
is greater than
.
