Question

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.

Answer 1

a=v²/2s
v= v₀-at
v=0
t= v₀/a

Answer 2

Not really helping much. A slightly worked example would be effective. But thanks anyway.

Answer 3

a=v²/2s = 40²/2•860=0.93 m/s²
v= v₀-at
v=0
t= v₀/a =40/0.93 =43.01 s.

Answer 4

Yes, thank you. I worked it out, after a few minutes. Anyway, thank's a lot :)

Answer 5

A plane is traveling down a runway at 20 m/s. If the runway is 1000 meters long and the plane begins to accelerate at 10 m/s2, how long does it take the plane to clear the runway?
