The displacements of the three strokes are as follows: d, = 4.00 m the north, d = 1.90 m northeast, and d; = 1.10 m at 0 = 25.0 west of south, as shown in the figure. If the golfer had made the hole in a single shot, what would be the displacement of the ball? (Assume the positive y- and x-axes are in the north and east directions, respectively.
