A box, initially at rest on the ground, is lifted straight upin the air by a rope, moving straight up at constant speed. When it's gotten pretty high off the ground, the rope is released,and the box falls back to the ground. Sketch a graph of the total force acting on the box from the start of that motion to the finish.
