Answer
(a) $I = 0.012~kg~m/s$
(b) $I = 0.012~kg~m/s$
Work Step by Step
(a) $I = \frac{1}{12}~mL^2$
$I = \frac{1}{12}(0.400~kg)(0.600~m)^2$
$I = 0.012~kg~m/s$
(b) Since each part of the rod's mass is still the same distance from the axis of rotation, the moment of inertia does not change.
$I = 0.012~kg~m/s$
