The magnitude of the angular momentum of the rod immediately after the collision is given as (pf + pi) * d. (Option A).
<h3>What is Angular Momentum?</h3>
Angular Momentum may be defined or described as the vector quantity of the rotation of a body, which is arrived at by multiplying its moment of inertia by its angular velocity.
The formula for Angular Momentum is given as:
L = <em>mvr; Where
L = Angular Momentum</em>
<em>m = mass</em>
<em>v = velocity; and </em>
<em>r = radius.</em>
