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 isreleased from the same point on the same inclined board, it travels a distance of 20 cm onfloor B before coming to rest. Which floor, A or B, offers greater friction? Give reasonfor your answer.
b offers greater friction...because as friction opposes the motion of an obtect and on floor b the motion of the object stop before floor a...that's why b offers more friction force...
