Explanation of an angular momentum term

  1. Oct 24, 2013 #1
    Hello, could somebody please explain to me why in 4 of these solutions, the angular momentum final term about point p is mVfR + Icmω ? It is in huge attached solutions my teacher posted.

    Thank you very much in advance

    Here is the problem in case you are interested of Horne context.

    4. A solid ball of radius are initially slides without rotating on a horizontal surface with a variable coefficient of friction. If the initial speed is Vo, find the speed when the ball begins to roll without slipping. Also find the energy lost due to friction

    I understand the angular momentum is conserved but I don't understand the final term in the angular momentum. I can't find out anything, it's bewildering me.
