33.8 m east, and finally 50.7 m in a direction

50.9◦ north of east.

Find the magnitude of the displacement re-

quired to bring the skater back to her starting

point.

33.8m[0o]

50.7m[50.9o]

X=16.9*cos225+33.8+50.7*cos50.9=53.8 m.

Y=16.9*sin225+0+50.7*sin50.9 = 27.4 m.

tan A = Y/X = 27.4/53.8 = 0.50921

A = 27o

D = X/cos A = 53.8/cos27 = 60.38 m.
