A dock worker pushes a box with m = 3.80 kg a distance d = 6.60 m along the floor by a constant force of magnitude F = 16.0 N directed at an angle ? = 21.0° below the horizontal as shown in the figure. Assume the floor is frictionless. (enter your answers in joules.) Determine the work done on the box by: the applied force (the force on the box exerted by the dock worker), the normal force exerted by the floor; the gravitational force; and the net force on the box.
