INFO

A golfer takes three putts to get the ball into the hole. The first putt displaces the ball 3.6 m exactly north. The second pur displaces the ball

2.2 m exactly southeast (i.e., 45 degrees south of east), and the third 0.8 m exactly southwest (i.e., 45 degrees south of west). What are the

magnitude and direction of the displacement needed to get the ball into the hole on the first putt? (State direction as angle north of east).

Suggested strategy:

(a) Sketch the displacement vectors in such a way that you understand the big picture of what is happening.

(b) Define a system of coordinates (i.e., the x and y axes) and redraw the displacement vectors so that it is easy to visualize their

degrees
