Problem1a

An aircraft flies West to East (= angle 90) with a true airspeed (as measured by its Pitot tube) of 150MPH,whereas the wind bloww South to North (= angle 0) with a velocity of 30 MPH. A sequence of 3 operations gives the result: drift angle and ground speed (as measured by radar for instance).
