A metre stick is pivoted about its centre. A piece of wax of mass 20 g travelling horizontally and perpendicular to it at 5 m/s strikes and adheres to one end of the stick so that the stick starts to rotate in a horizontal circle. Given the moment of inertia of the stick and wax about the pivot is 0.02 kg `m^(2)`, the initial angular velocity of the stick is :

A. 1.58 rad/s
B. 2.24 rad/s
C. 2.50 rad/s
D. 5.00 rad/s
