A 15kg block slides up a 30∘ inclined plane at a constant velocity. The coefficient of friction between the block and the plane is μk=0.2. In order for the block to slide up the incline, someone must apply a force to the block. What is the magnitude of the applied force if it points parallel to the incline? What is the magnitude of the applied force if it points horizontally instead?
