The figure shows an overhead view of a 1.70 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 59.0 g slides toward the opposite end of rod with an initial velocity of 37.5 m/s. The disk strikes the rod and sticks to it. After the collision, the rod rotates about the pivot point. disk pivot (a) What is the angular velocity, in rad/s, of the two after the collision? x What is the angular momentum of an object moving with a linear velocity, about a given point? rad/s (b) What is the kinetic energy, in joules, before and after the collision? KE 41.9 KE, 0.804 x Initially the disk has translational motion while after collision the disk and stick have rotational motion. J
