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 axis of the cylinder.

(a) Draw a diagram showing the cylinder and the rotation axis.

(b) What is the moment of inertia of the cylinder about the axis of

rotation?

(c) If the cylinder is released from rest with its central longitudnal

axis at the same height about which the cylinder rotates, what is

the angular speed of the cylinder as it passes through its lowest

position? (Hint: see Table 10-2 of your textbook. The central

longitudnal axis is pictured in panel c.)

A very thin 2.0-kg disk with a diameter of 80 cm is mounted horizontally to rotate freely about a central vertical axis. On the edge of the disk, sticking out a little, is a small, essentially massless, tab or "catcher." A 2.0-g wad of clay is fired at a speed of 14.0 m/s directly at the tab perpendicular to it and tangent to the disk. The clay sticks to the tab, which is initially at rest, at a distance of...
