d1 = (0,3.98)
d2 = (2.01/√2,2.01/√2)
d3 = (-1.12/2,-1.12√3/2)
just add them up and convert back to compass directions.
A novice golfer on the green takes three strokes to sink the ball. The successive displacements of the ball are d1 = 3.98 m to the north, d2 = 2.01 m northeast, and d3 = 1.12 m at 30.0° west of south (see the figure). Starting at the same initial point, an expert golfer could make the hole in what single displacement?
