Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures.  A pendulum is constructed by attaching a non-uniform disk of mass M and radius R to a uniform stick of mass 4M and length 3R (see sketch). The surface density of the disk is given by ï³ = a r2,

where r is the distance from the diskâs center and a is a constant that can be determined and

written in terms of M and R. The other end of the stick is attached to a frictionless pivot. With the pendulum held in a horizontal position, it is released from rest. When the pendulum makes an angle of 30ï° with the vertical, findâ¦

A. The angular acceleration of the pendulum. B.  The tangential speed of the center of mass. C. The force (magnitude and direction) exerted by the pivot on the pendulum.
