A fan blade of length \(L\) with a dust speck located at a distance \(r\) from the axis.
A fan blade of length \(L\) with a dust speck located at a distance \(r\) from the axis.
A fan with blades of length \(L\) rotates at a constant rate about its center. A small speck of dust is located on one of the blades at a distance of \(\dfrac{2}{3}L\) from the axis of rotation. The fan is observed to complete \(N\) full revolutions in a time interval \(\Delta t\). Which of the following is a correct expression for the speed \(v\) of the speck of dust?
