    a=v²/2s
    v= v₀-at
    v=0
    t= v₀/a

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

    a=v²/2s = 40²/2•860=0.93 m/s²
    v= v₀-at
    v=0
    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 :)
