1. The problem statement, all variables and given/known data An airplane has a speed of 265 km/h relative to the air. There is a wind blowing at 90 km/h at 30° north of east relative to Earth. In which direction should the plane head to land at an airport due north of its present location(in degrees west of north)? What is the plane's speed relative to the ground (km/h)? 2. Relevant equations Vx0 = V0cos(O) Vy0 = V0sin(O) 3. The attempt at a solution VwindE = 90cos(30) = 77.9 km/h VwindN = 90sin(30) = 45 km/h I am trying to figure out what to do from here. It says that the plane's velocity is 265 km/h, but it doesn't say which way the plane is going. I am clueless on what to do to get the direction the plane should head. I know I don't have a lot of steps, but I'm completely stuck.
