Answer:

 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.
