Hello everyone,
as my name suggests I love physics. Currently i am trying to get into physics again and find myself stuck with this problem.
I would really appreciate if you gave me advice on just how to approach this problem, coz I really want to solve it myself.
Problem
You are flying in a light airplane spotting traffic for a radio station. Your flight carries you due east above a highway. Landmarks below tell you that your speed is 57.0 m/s relative to the ground and your air speed indicator also reads 57.0 m/s. However, the nose of your airplane is pointed somewhat south of east and the station's weather person tells you that the wind is blowing with speed 20.0 m/s.
In which direction is the wind blowing? Express your answer as an angle measured east of north.
End.
Please guys I just need a starting point. Could it be that I could add or substract the velocities vectorially and then use the cosine rule in order to finally get the degrees?
I believe that since the nose is pointing south of eaast there must be a 45 degree angle.
Am I right?
wait. or could it be that i have to approach this problem from the frame of reference of the Earth then add the vel. vectors and obtain the degrees? since there is a steady wind?
