    The constant force required is 17.6 N

    Explanation:

    Given-

    Mass, m = 0.55 kg

    Initial speed, u = 0

    Final speed, v = 8 m/s

    Time, t = 0.25 s

    Force, F = ?

    We know,

    Force = mass X acceleration

    F = 0.55 X \frac{v}{t}

    F = 0.55 X \frac{8}{0.25}

    F = 17.6 N

    Therefore, the constant force required is 17.6 N
