You are standing on the ground at the origin of a coordinate system. An airplane flies over you with constant velocity parallel to thexaxis and at a constant height of9.2010³m. At

t= 0,

the airplane is directly above you so that the vector leading from you to it is

P₀=9.2010³m.

At

t= 30.0 s

the position vector leading from you to the airplane is

P₃₀= (9.0810³+9.2010³) m

as suggested in the figure below. Determine the magnitude and orientation of the airplane's position vector at

t=65.0s.
