Assuming take off speed is 60kts, when you take off into a headwind of 50 knots, would you take off if you applied 10kts of power or would you still need to add 60kts of power?
You should not talk about "60kts of power" or "10kts of power". It is misleading as well as physically meaningless.
You should talk about "The power needed to offset the drag of the aircraft at an airspeed of 60 kt" (or 10 kt, as the case may be).
