You are standing on the ground at the origin of a coordinate system . An airplane flies over you with constant velocity parallel to the x axis and at a fixed height of 7.60 x 10^3 at time t = 0 the airplane is directly above you , so that the vector leading from you to it is , P0 = (7.60 x 10^3 ) j . At t = 30.0 s the position vector leading from you to the air plane is P30 = (8.04 x 10^3 m) i + (7.60 x10^3 m)j . Determine the magnitude and orientation of the airplane position vector at t = 45.0 s .
