    Work done by the little rocket engine = 19.6 Joules.

    Explanation:

    We know that work = force x displacement.

    Force = weight of rocket = 4.9 N

    Displacement = 5 meter.

    So work done by the little rocket engine = Weight of rocket x displacement.

    Work done by the little rocket engine = 4.9 x 4 = 19.6 J

    Work done by the little rocket engine = 19.6 Joules.
