Quizplus · Accepted Answer

Average angular acceleration is given by the formula:
average angular acceleration = (change in angular velocity)/(time interval)
From the graph, we can see that the change in angular velocity between t=6 min and t=8 min is (4 rad/s - 0 rad/s) = 4 rad/s. The time interval is (8 min - 6 min) = 2 min = 120 s. Therefore, the average angular acceleration is:
average angular acceleration = (4 rad/s)/(120 s) = 0.0333 rad/s^2 ≈ 11ea7ff9_2b19_3d49_a768_3970fe9f2875_TB2295_11
