A uniform thin rod of mass m and length L is rotating on a smooth horizontal surface with one end fixed. Initially it has an angular velocity S and the motion slows down only because of air resistance which is k dx times the square of the velocity on each element of the rod of length dx . Find the angular velocity w after time t .

Solution:
A uniform thin rod of mass m and length L is rotating on a smooth horizontal sur
