Problem

Two different rigid objects, A and B, are tested under identical conditions. When

K_{\text{rot}}

is plotted versus

\omega^2

, the straight-line fits yield slopes of

0.050\,\text{J}\,(\text{rad/s})^{-2}

for object A and

0.20\,\text{J}\,(\text{rad/s})^{-2}

for object B. Calculate the ratio

I_B/I_A

of their moments of inertia.
