Homework Statement
The problem is worded thus:
You are on an airplane traveling 30° south of due west at 130 m/s with respect to the air. The air is moving with a speed 30 m/s with respect to the ground due north.
(a) What is the speed of the plane with respect to the ground?
(b) What is the heading of the plane with respect to the ground? (Let 0° represent due north, 90° represents due east).
Homework Equations
No formulas given
The Attempt at a Solution
I attempted to solve the problem by putting it on a N-E coordinate plane, with two vectors. (North as y, east as x).
For wind:
[tex] \vec{v} = 0\hat{i} + 30\hat{\jmath} [/tex]
For the plane, I do not know how to set up a vector. My plan was to do so, and then find its magnitude so that I can find the plane's speed relative to the ground. 130 m/s is given as the plane's speed relative to the air, but I need to figure out how to relate that to the ground. Any ideas?
For part b, I think I need to know how to do "a" first.
