A block is pulled at constant speed along a rough level surface by a rope that makes an angle of 30° with respect to the horizontal. The applied force along the rope is p. The force of kinetic friction between the block and the surface is 20 N. 30 Which one of the following expressions gives the magnitude of the force P in SI units?
