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.
