See Answer Web9 de out. de 2005 · I think I will answer the task by saying: " Friction can't do positive work, because: (1) In the case of kinetic friction: Kinetic friction always oppose motion so. W = F*d*cos (x>90 degrees) = - F*d. (2) In the case of static friction: Their is no displacement and therefore no work is done. phillips hollow metal
