Balls with a mass of 2 kg are attached to the two ends of a 200 cm long thin rod of negligible mass. The rod can rotate freely about a vertical axis without friction that passes through its center in the horizontal plane. While the stick is in its original state, a 200g mass of sticky putty balls hit each other at 5 m / s and stick together. a) What is the angular velocity of the system after the paste hits? b) What is the ratio of the kinetic energy of the system after the collision to the kinetic energy of the paste just before the impact?

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
