Problem M. 418. (December 2022)

M. 418. Measure the rotational inertia of a ball (e.g. football, table tennis ball or tennis ball) by rolling it down a slope. Give the result also in units of \(\displaystyle mR^2\) (where \(\displaystyle R\) is the radius of the ball, \(\displaystyle m\) is its mass). Can the result be used to infer the thickness of the wall of the ball?
