Question

If an airplane is flying directly north at 300.0 km/h, and a crosswind is hitting the airplane at 50.0 km/h from the east, what is the airplane's resultant velocity?

Answer 1

\[300^2+50^2=v^2\]

Answer 2

@joe4321 See the figure
the wind will change the orientation of the plane and hence it's velocity

Answer 3

Now the plane will move in this direction
its velocity V will be given as
\[V^2=300^2+50^2\]
\[V=\sqrt{300^2+50^2} km/h\]

do you understand this?
