That is, a vehicle following the spiral at constant speed will have a constant rate of angular acceleration. �26S075SI�r � . If this time was 4.00 s and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course? /BitsPerComponent 8 � � � Angular Acceleration of a Propeller Figure 10.12 shows a graph of the angular velocity of a propeller on an aircraft as a function of time.
