    Acceleration=Final velocity-Initial velocity / time.

    Acceleration=a=4m/s².

    Initial velocity = u = 44m/s

    Final velocity=v = let it be v, since we are to look for the final velocity.

    Time=t=10seconds.

    Mathematically:

    a=v-u/t

    Substituting the givens into the equation.

    4=v-44/10

    cross multiply.

    4*10 = v-44

    40=v-44

    40+44=v

    v=84m/s
