Question: A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle 30 degrees above the horizontal, as shown (Figure 6)

A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle 30 degrees above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, the coefficient of kinetic friction between the box and the plane is μk=0.30, and the displacement of the box is 1.8 m down the inclined plane.
