Pilots can be tested for the stresses of flying high-speed jets in a whirling "human centrifuge," which takes 1.8 min to turn through 21 complete revolutions before reaching its final speed.

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

2. What is the final angular speed in rpm?

Thanks in advance

Angular 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.
