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? (Use the graphical method to answer and include your scale on the graph paper.)

Answer 1

add the two vectors



find the magnitude of the sum by applying the pythagorean theorem
where magnitude = (x^2 + y^2) where x is the velocity in the x-direction (east) and y is the velocity in the y direction (northeast)
