The table that follows lists four pairs of initial and final angular velocities for a rotating fan blade. The elapsed time for each of the four pairs is 4.1 seconds. For each of the four pairs, find the average angular accelerations. Oo (1) -7 rad/s 5 rad/s |(2) 2 rad/s -8 rad/s |(3) -5 rad/s 11 rad/s (4) -3 rad/s -13 rad/s
