Twin skaters approach one another as shown in the figure below and lock hands. (a) Calculate their final angular velocity (in rad/s), given each had an initial speed of 2.70 m/s relative to the ice. Each has a mass of 92.0 kg, and each has a center of mass located 0.890 m from their locked hands. You may approximate their moments of inertia to be that of point masses at this radius. (Enter the magnitude.) (b) Compare the initial kinetic energy and final kinetic energy. Initial kinetic energy is greater than final kinetic energy. Initial kinetic energy is less than final kinetic energy. Initial kinetic energy is the same as final kinetic energy.

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.
