SUMMARY
Angular momentum is conserved, meaning the initial angular momentum of 7.87 must equal the final angular momentum. However, the average torque calculation is incorrect; it should account for the change in angular momentum over time. Given that the angular velocity of the rod changes from 0 to 26.03 rad/s in 7 seconds, the average torque is not zero, as the change in angular momentum is not zero.
