The diagram represents a ramp at a skateboard park : a quarter-circle arc of radius R (segment AB) joined to a horizontal section (segment BC). A skateboarder of mass M starts from rest at point A, rolls frictionlessly down arc AB, and collides with his friend (also same mass M) who is standing on the ground at rest at point B. The two people stick together in the collision. They fall over and together slide distance d along the horizontal surface before coming to a stop. The coefficient of kinetic friction along the horizontal segment is
