[单选题]
A pilot intends to fly a plane from point $A$ to point $B$. Due to strong winds, she points the nose of the plane in the direction shown by the vector $P$. Which of the choices below best represents the direction of the wind encountered by the plane?
A.
B.
C.
D.
参考答案: B
本题详细解析:
In order for the plane to travel from A to B, the resultant vector of the sum +;udn*ds4zg ooumy/g pq5f5+t6 :zhm of the wind vector and the vector of the orientation of the plane must point in the same direction as the vector from A to B, as shown in the diagram below. For any of the other choices, the resd5 p5z/4 o +smz;fuqt6gg:hn um+doy*ultant will not be in the direction A to B.
