    Answer:

    2.3125m/s²

    Explanation:

    Using the equation of motion v² = u²+2aS

    v is the final velocity = 120km/hr

    120km/hr = 120 * 1000/1 * 3600 = 33.3m/s

    u is the initial velocity = 0m/s

    a is the acceleration

    S is the distance covered = 240m

    On substituting the given parameters

    33.3² = 0²+2a(240)

    33.3² = 480a

    1110 = 480a

    a = 1110/480

    a = 2.3125m/s²

    Hence the minimum constant acceleration that the aircraft require to be airborne after a takeoff run of 240 m is 2.3125m/s²
