Problem 19P

A cooling fan is turned off when it is running at 850 rev/min. It turns 1500 revolutions before it comes to a stop. (a) What was the fan’s angular acceleration, assumed constant? (b) How long did it take the fan to come to a complete stop?

Step-by-Step Solution:

Step 1 of 3

Part (a)

The following are given by the question:

The frequency of the revolution of the fan,

Angle

The final angular velocity,

We know

Here, is the final angular velocity, is the initial angular velocity and is the angular acceleration.

Step 2 of 3
