A plane is heading west at 200 mph. The wind is blowing S30W at 25 mph.

1. What is the ground speed of the plane?


2. When you solve the triangle, what is the smallest angle?


3. What is the largest angle of the triangle?


4. What is the remaining angle?


5. What is the bearing of the plane?


A plane is is flying 240 mph heading N60E. The wind is blowing S30E at 30 mph.

6. What is ground speed of the plane?


7. What is the smallest angle in the triangle?


8. What is the biggest angle in the triangle?


9. What is the remaining angle in the triangle?


10. What is the bearing of the plane?


A plane is is flying 225 mph heading S25W. The wind is blowing S80E at 60 mph.

11. What is the bearing of the plane?


12. What is the smallest angle of the triangle?


13. What is the largest angle of the triangle?


14. What is the remaining angle of the triangle?


15. What is the ground speed of the plane?


16. Vector A has a magnitude of 3 in the leftward direction and B has a magnitude of 5 in the rightward direction. What is the value of 2A B?



You can also answer other types of problems using vectors. Try this one:

Two forces are pushing on an object, one at 12 lbs of Force and one at 5.66 lbs of Force. The angle between them is 35 (each is 72.5 from horizontal, such that the forces make a v with the object in the center).

17. What is the total Force on the object?


18. What is the smallest angle of the triangle?


19. What is the largest angle in the triangle?


20. What is the remaining angle of the triangle?
