OK, I've been thinking about these specific problems alot lately.. Hope someone can help clarify how I should understand how to go about these kinds of questions.. Let's say an airplane is moving at some angle x degrees with respect to the east (Stupid way to describe the direction, please don't blame me. :P) and it's moving at a velocity v... Let's say the wind is blowing, hmm, south... Because of the wind, wouldn't the plane be moving in another direction, which would mean it would never ever ever reach its destination s meters away at the direction it was supposedly to travel in unless it were to change its route? This is where I'm wondering how to solve problems like... Say a person is walking with velocity magnitude 20m/s at 53 degrees and there's a wind vector w = -5i m/s which is applied to this person.. Let's pick an arbitrary distance, err... 300m that he is from his destination.. How would we find the time it takes for him to get to his destination? I was thinking finding the x and y components to his velocity and adding up the two vectors and finding the resultant and dividing 300m by it, but that resultant velocity would be in a whole new direction! This is really confusing me... I really want to learn how to approach these problems... I'd appreciate it if someone could help me out.. (and perhaps provide examples of these kinds of problems) Thanks.
