Question #405

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

Merged questions

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 ﻿﻿
