How Do You Calculate the Effective Speed of a Tailwind for a Westward Cyclist?

[QUOTE="CAF123, post: 4515896, member: 419343"] Yes, you can represent the velocity vector of the cyclist as ##\vec{C} = -5.6 \hat{x}## and that of the wind as ##\vec{W} = (10 \cos 45)\hat{x} + (10 \sin 45) \hat{y}##. Now, as you said, just add components to get the resultant. From a more conceptual point of view, imagine a game of tug of war. Person A pulls to left with force 5.6N and person B to right with force 10cos45 ≈ 7.1 N. The person pulling to right wins, but only marginally. (winning by 7.1 - 5.6, not 7.1 + 5.6) [/QUOTE]
