Two Stage Rocket
Suppose the motion of the two-stage rocket or the corresponding velocity-time graph below. The rocket has two successive fuel stages followed through a free-fall motion (no fuel). Within the two fuel stages, the rocket experiences an upward acceleration of +10 m/s/s and +4.29 m/s/s correspondingly. This acceleration is depicted through the slope on the velocity-time graph.
suppose you are running and want to stop at once. surely you will have to produce negative acceleration in your speed. can you tell from where does the necessary force come ?
