Question

An airplane flies at an altitude of 36,000 km and is traveling at a velocity of 300.0 km/h to the north, but the tailwind is 20.0 km/h. What is the airplane's final velocity? (Remember that velocity is a vector.)

Answer 1

positive tailwind in the same direction as the plane --> simply add the plane's velocity and the tailwind velocity. make sure your solution is in km/h

altitude is not relevant for this problem

Answer 2

velocity wrt what?

all motion is relative
