So, for angular momentum, if angular momentum is constant, then initial angular momentum = final angular momentum.

But, what if there is a net torque? How do you take that into account when calculating the final angular momentum?

In general, torque can be thought of as a rate of change in angular momentum.

For the case where there is an external torque, then;

Initial L + delta L = Final (L)

To find delta L (change in angular momentum) you need to know the time over which the torque was applied.
