You are traveling on an airplane. The velocity of the plane with respect to the air is 100.0 m/s due east. The velocity of the air with respect to the ground is 36.0 m/s at an angle of 30° west of due north.
1) What is the speed of the plane with respect to the ground? _____________m/s?
2) What is the heading of the plane with respect to the ground? (Let 0 degrees represent due north, 90degrees represents due east) ________________. degrees East of due North ???
3) How far east will the plane travel in 1 hour? _____________m ?
