a. What is the angular velocity, in rad/s, of the two after the collision?

b. What is the kinetic energy, in joules, before and after the collision?

The figure shows an overhead view of a 2.10 kg plastic rod of length 1.20 m on a table. One end of the rod is attached to the table, and the rod is free to pivot about this point without friction. A disk of mass 46.0 g slides toward the opposite end of the rod with an initial velocity of 34.5 m/s. The disk strikes the rod and sticks to it. After the collision, the rod rotates about the pivot point. disk pivot
