Asked by Josh
1) Imagine you were to walk 12 km 25 degrees North of East. If you could only walk south and west to get back to the point that you started from, how far would you have to walk?
2) An airplane has a velocity of 70 m/s [50 degrees W of N] with respect to the air. A person on the ground looks up and observes velocity of the airplane to be 60 m/s [20 degrees N of W], what was the velocity of the wind?
Help with either of these question would be greatly appreciated.
