A sphere of radius R and mass M is initially spinning about its center with a given angular velocity of omega. The axis of its rotation is horizontal and therefore parallel to the table. It is then placed on the level table with its center of mass velocity zero and there is kinetic friction between the sphere and the table. Find how far the sphere travels before it stops slipping. Find how much time this takes and find the final speed of the sphere's center of mass at that time.
