Question #405

A fan starts from rest and attains speed of 4 rev/min in 2 mins. Then, find its angular acceleration.

Answer

To find the angular velocity of a fan reaching 4rev/min in two minutes, let's start by converting the speed to radians per second:








From the previous, we can now calculate the average acceleration:





In conclusion, the average angular acceleration is
