When a pencil cell is released from a certain point on an inclined wooden board, it travels a distance of 35 cm on floor A before it comes to rest. When the same pencil cell is released from the same point on the same inclined board, it travles a distance of 20 cm on floor B before coming to rest. Which floor, A or B, offers greater friction?
