Problem
A 12kg toolbox is dragged up a 25∘ incline at constant speed by a rope that makes the same 25∘ angle with the surface and pulls parallel to the incline. The coefficient of kinetic friction between the toolbox and the surface is μk=0.22. Calculate the magnitude of the pulling force exerted by the rope.
