1. The problem statement, all variables and given/known data An airplane is flying at an airspeed of 620 km/hr in a cross wind that is blowing from the northeast at a speed of 50km/hr. In what direction should the plane head to end up going due east? 2. Relevant equations v+w=(xi+yj), trig identities 3. The attempt at a solution I think the j component is equal to 25sqrt(2) but I don't understand where the airspeed fits into finding the direction the plane should head.
