PRACTICE ANOTHER The figure shows an overhead view of a 2.20 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 450 g slides toward the opposite end of the rod with an initial velocity of 26.0 m/s. The disk strikes the rod and sticks to it. After the collision, the rod rotates about the pivot poist plo (e) What is the angular velocity, in rad/s, of the two after the collision? rad/s (b) What is the kinetic energy, in joules, before and after the collision? KE
