An aircraft has a lift-off speed of 120 km/hr. What minimum constant accelerationdoes this require if the aircraft is to be airborn after a take-off run of 240 m?

  • Physics -

    change 120km/hr to m/s


    V^2=2a*240 find a

  • Physics -

    120 km/h = 33.3 m/s

    V = sqrt(2aX) = 33.3 m/s

    Solve for the acceleration, a.
    X = 240 m.
