The figure shows four vectors, , , , and , having magnitudes 20.0 m, 5.0 m,10.0 m, and 9.0 m, respectively. The sum of these four vectors is
A.11.2 m at an angle 33.6° with respect to +x-axis.
B.19.5 m at an angle 12.3° with respect to +x-axis.
C.19.5 m at an angle 77.8° with respect to +x-axis.
D.16.4 m at an angle 12.3° with respect to +x-axis.
E.8.20 m at an angle 77.8° with respect to +x-axis.
An jet flies between two points on the ground that are 500 km apart with an airspeed of 200 m/s. The destination is directly north of the point of origin of the flight.. If a constant wind blows at 10 m/s toward the west during the flight, what direction must the plane fly relative to the air to arrive at the destination?
A.5.9° east of north
B.2.9° east of north
C.2.9° west of north
D.5.9° west of north
E.85° west of north
