    Final velocity is 13.37 m/s

    Explanation:

    We have equation of motion v = u + at

    Initial velocity, u = 7.3 m/s

    Final velocity, v = ?

    Time, t = 7.4 s

    Acceleration, a = 0.82 m/s²

    Substituting

    v = u + at

    v = 7.3 + 0.82 x 7.4

    v = 13.368 m/s

    Final velocity is 13.37 m/s
