3.5 Exercise 14

Avg difficulty 2.5

(a) Another airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 20º\text{20}º south of east (as in the exercise). Its direction of motion relative to the Earth is 45.0º45.0º south of west, while its direction of travel relative to the air is 5.00º5.00º south of west. What is the airplane’s speed relative to the air mass? (b) What is the airplane’s speed relative to the Earth?
