A spacecraft was designed to assess the ability of an impact to deflect the path of an asteroid. The spacecraft was launched on a rocket. At launch, the rocket has a mass of 555,000 kg and generates a force of 7.6 x 106 N. A. If you were to neglect the effect of gravity, what would the intial acceleration of the rocket be? B. If the acceleration were to remain constant, how fast will the rocket be moving after two seconds? C. As the rocket burns fuel its mass decreases. If the thrust remains the same, how would your answer to part B change? Would the speed after two seconds be lower, the same or higher?
