Answer

Brief Explanations:

  • First law: The rocket was at rest before launch (law of inertia - an object at rest stays at rest until acted on by an external force).
  • Second law: Given mass ($m = 2.9$ kg), acceleration ($a=15.3$ m/s²) and force ($F = 44$ N), $F=ma$ is demonstrated.
  • Third law: The hot - gases pushed out from the rocket engine nozzle (action) and the rocket is propelled upward (reaction). There are only three Newton's laws, so fourth and fifth laws do not exist.

Answer:

the first law, the second law, the third law
