A pendulum consists of a disk of mass, m, and radius, r, connected to a pivot point via string (of negligible mass) of length, l. Note, the disk hangs vertically and the string is attached to its top. For small angles, derive an expression for:
(a) angular position as a function of time
(b) angular velocity as a function of time
(c) angular acceleration as a function of time

A grandfather clock has a pendulum that consists of a thin brass
disk of radius 37 cm and mass 1.6 kg that is attached to a long,
thin rod of negligible mass. The pendulum swings freely about an
axis perpendicular to the rod and through the end of the rod
opposite the disk. The pendulum should be designed so that its
period is 2 s for small oscillations when the gravitational
acceleration is 9.8 m/s2.
