5. A 2.5 kg block is initially at rest on a horizontal surface. A 6 N horizontal force and a vertical force P are applied to the block. The coefficient of friction for the block and surface are s-0.40 and pk-0.25. Determine the magnitude and direction of the frictional force acting on the block if the magnitude of P is 8N
