The airplane can take off when its airspeed (speed of the air flowing over the wing) is equal to 65 knots. What is the length of runway required for the plane to take off if there is a 13 knots head wind? The runway at the Tallahassee Regional Airport has a length of 8000 ft.
I'm not sure what I'm doing wrong.I've already converted the knots to meters/second and the feet to meters. The equation I'm using to find the acceleration is 33.41^2=2a(2438.4). Next, I subtracted the 6.682m/s from 33.41m/s to get the ground speed. I then used the equation 6.682^2=2(.23)d to find the length of the runway, but my answer is still incorrect.
