2 You are standing on the ground at the origin of a coordinate system.
3 An airplane flies over you with constant velocity parallel to the $x$
4 axis at a fixed height of $7.60\E{3}\U{m}$. At time $t=0$, the
5 airplane is directly above you so that the vector leading from you to
6 it is $\vect{P}_0=7.60\E{3}\jhat\U{m}$. At $t=30.0\U{s}$, the
7 position vector leading from you to the airplane is
8 $\vect{P}_{30}=(8.04\E{3}\ihat+7.60\E{3}\jhat)\U{m}$ as suggested in
9 Figure P3.43. Determine the magnitude and orientation of the
10 airplane's position vector at $t=45.0\U{s}$.
