2) An aircraft lands on a runway at a speed of 40 meters per second (ms^-1) and brakes to a halt in a distance of 860m. Calculate a) The Braking time. B) The deceleration of the aircraft.
Not really helping much. A slightly worked example would be effective. But thanks anyway.
a=v²/2s = 40²/2•860=0.93 m/s²
t= v₀/a =40/0.93 =43.01 s.
Yes, thank you. I worked it out, after a few minutes. Anyway, thank's a lot :)
