An object consists of a rod (of length 3.00 m and negligible moment of inertia) to which four small 3.50-kg masses are attached, one at each end and one at each point on the rod spaced at 1.00-m intervals. The moment of inertia of this object about an axis perpendicular to the rod and through one of the end masses:
a. is 49 kg·m2.
b. is 21 kg·m2.
c. is 31.5 kg·m2.
d. is 10.5 kg·m2.
e. cannot be uniquely determined until it is stated which inner mass the axis goes through.
