A uniform cylinder of radius 10 cm and mass 20 kg is mounted so as to rotate freely about a horizontal axis that is parallel to and 5.0 cm from the central longitudinal axis of the cylinder. (a) What is the rotational inertia of the cylinder about the axis of rotation? (b) If the cylinder is released from rest with its central longitudinal axis at the same height as the axis about which the cylinder rotates, what is the angular speed of the cylinder as it passes through its lowest position?

Question
A uniform cylinder of radius 10 cm and mass 20 kg is
mounted so as to rotate freely about a horizontal axis that is parallel
to and 5.0 cm from the central longitudinal axis of the cylinder.
(a) What is the rotational inertia of the cylinder about the axis of
rotation? (b) If the cylinder is released from rest with its central
longitudinal axis at the same height as the axis about which the
cylinder rotates, what is the angular speed of the cylinder as it
passes through its lowest position?
