An object slides on an inclined plane that has a slope of 30 degrees. The height of one end of the inclined plane relative to the other end is 2.0 m. The mass of the object is 2.5 kg and the coefficient of kinetic friction between the object and the plane is 0.2. How much work is done by the force of gravity when an object moves from the top to the bottom of an inclined plane?
