4. A 50-kg trunk is pushed a distance of 6 meters at a constant speed up an incline of 30-degrees by a constant force. The coefficient of kinetic friction between the trunk and the incline is 0.2. Calculate the work done by (a) the applied force, (b) the frictional force, and (c) the gravitational force.
