A commuter airplane starts from an airport and takes the route shown in the figure below. The plane first flies to city 4, located 175 km away in a direction 30.0 north of east. Next, it flies for 150 km 20.0 west of north, to city B Finally, the plane flies 190 km due west, to city C.Find the location of city C relative to the location of the starting point 200 20.0° 110° 050 100 150 200

Explanation / Answer

a) x-component of vector A is Ax = -A*sin(30) = -12*0.5 = -6

b) y-component of vector A is Ay = A*cos(30) = 12*cos(30) =10.4

c) Bx = -B*sin(10) = -8*sin(10) = -1.38

D) By = -B*cos(10) = -8*cos(10) = -7.87

e) Cx = Ax+Bx = -6-1.38= -7.38

Cy = 10.4-7.87 = 2.53

f) Dx = -Cx = 7.38

Dy = -Cy = -2.53
