A novice golfer on the green takes three strokes to sink the ball. The successive displacements of the ball are 4.00 m to the north, 2.00 m north east, and 1.00 m west of south. Starting at the the same initial point, an expert golfer could make the hole in what single displacement?

2. Relevant equations

3. The attempt at a solution

get the x- and y- components of each vector. then get the summation of the x and y component.. then use

R = $\sqrt{(Ʃ_{x}^2 + Ʃ_{y}^2)}$

to get the angle.. use $θ = tan^-1 \frac{Ʃ_{y}}{Ʃ_{x}}$
