In Example 11.9, we investigated an elastic collision between a disk and a stick lying on a frictionless surface. Suppose everything is the same as in the example except that the collision is perfectly inelastic so that the disk adheres to the stick at the endpoint at which it strikes. Find (a) the speed of the center of mass of the system and (b) the angu- lar speed of the system after the collision.

![Example 11.9
Disk and Stick Collision
m
A 2-kg disk traveling at m/s strikes a-kg stick of
lengthm that is lying flat on nearly frictionless ice as
shown in the overhead view of Figure 11.12a. The disk strikes
at the endpoint of the stick, at a distance r = m from
the stick's center. Assume the collision is elastic and the disk
does not deviate from its original line of motion. Find the
translational speed of the disk, the translational speed of the
stick, and the angular speed of the stick after the collision.
The moment of inertia of the stick about its center of mass is
kg m².
