mechanics problem: rod rolling of a step

rayf

Hello i am having trouble understanding what would be the angular and linear velocity of the center of mass of a rod that falls of a step and hits the ground and continues rolling. I know that mechanical energy is not conserved after the rod hits the ground, as that would be an inelastic collision, also angular momentum is not conserved as there is friction acting to rotate the rod once it hits the floor. I am also aware that the rod will roll and move while slipping till v=wr but how can i determine an equation so that i can know when one velocity will decrease and the other increase until they are equal.
