1. What is the angular acceleration?(rev/min^2)

2. What is the final angular speed in rpm?

Thanks in advance

**drwls**, Monday, March 5, 2012 at 10:22pmAngular acceleration is usually expressed in radians/s^2 and angular speed in radians/s.

In your case, 21/1.8 = 11.67 is the average speed in rev/min. The final speed is twice that, or 23.33 rev/min

The angular acceleration is 23.33 rev/min divided by 1.8 min, which is 12.96 rev/min^2.
