Expert Answer:

Please post one query at a time.
Angular velocity of a rigid body is the rate of change of its angular position. Thus, if = at t = t1 , and = at t = t2 ,??????the average angular velocity is
?
 
Angular Acceleration is the rate of change of angular velocity with time. he average angular acceleration is given by
