Calculate the moment of inertia of a baseball bat for the following cases.
(a) Assume the bat is a wooden rod of uniform diameter and take the pivot point to be in the middle of the bat, at the end of the bat, and 5 cm from the end of the handle, where a batter who "chokes up" on the bat would place his hands. Hint: Consider the bat as two rods held together at the pivot point. Estimate the mass of the bat.
kg
Estimate the length of the bat.
