Problem2: A rocket is initially at rest on the surface of an unknown planetary body. The rocket engine is then ignited and it provides an upward thrust force that grows steadily as time goes on. The mass of the rocket be treated as being constant over the period of time being considered. A graph of acceleration vs thrust force is shown here for the liftoff of the rocket.
