Question

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 m2, the initial angular velocity of the stick is​

Answer 1

Answer:

Angular velocity =2.5 rad/s

Explanation:

Angular momentum = I × angular velocity  

20×10^-3×5×0.5=2×10^-2× angular velocity  

Angular velocity =2.5 rad/s
