Answer:
The angular velocity of the propeller is 2.22 rad/s.
Explanation:
The angular velocity (ω) of the propeller is:  
 
                              
Where:
θ: is the angular displacement = 10.6 revolutions 
t: is the time = 30 s 

Therefore, the angular velocity of the propeller is 2.22 rad/s.
