1. The problem statement, all variables and given/known data An airplane is flying toward the Southeast with a speed of 200 m/s, and the wind is blowing toward the Northeast with a speed of 60 m/s. A. Which direction will the plane head now? B. What is the groud speed of the plane? 2. Relevant equations 3. The attempt at a solution I thought that the ground speed was determined by the vector of the wind and the plane, but I can't figure out how to find the direction.... I thought about taking the arctan of the two values I was given, but I didn't think that would work because I did not know which should be the x and y values, and they are going different directions. Can anyone explain to me how to set this problem up?
