    Answer: Velocity=8.26m/s

    Explanation:

    Acceleration=Finial velocity (V) - Initial velocity (u) : Time

    that is, a=v-u/t

    a=1.2m/s², v=?, u=5.5m/s, t=2.3s

    From a=v-u/t, make v the subject of the formula

    v=at + u

    v = (1.2 * 2.3) + 5.5

    v=2.76+5.5

    v=8.26m/s
