The Warrior can take off when its airspeed (speed of the air flowing over the wing) is equal to 100 km/hr. What is the length of runway, in meters, required for the plane to take off if there is a 12 km/hr head wind? Note: the shortest runway at the Rochester International Airport has a length of 1000 m. Take the acceleration from the the answer of the previous question. The acceleration from past problem was .444444444444444m/s^2 Okay so first I set 100=-12+.444444444t then 112=.444444444t convert 112 to m/s 31.1111111=.4444444444t t=70 then I use that time in x=-3.333t+(1/2)(.44444444)t^2 and solve for x right? and I get 855.57m as the length of the runway but this is incorrect so where exactly is my mistake?
