Directions: Consider the following scenarios ignoring the effects of gravity:
1. You are the capitan of a spacecraft traveling in the far reaches of outer space, a great distance from any other body. Unexpectedly your radar indicates a meteor on a collision course with your craft, necessitating a sudden change of speed and direction. Explain, in simple but physically correct terms, the mechanism that your craft uses to enable you to (i) alter your direction and (ii) change (increase or decrease) your speed.
2. After completing this maneuver you resume your initial direction and speed. Suddenly all engine power is lost for two hours. Explain what happens to the motion of your craft when the power is lost and during this time period.
3. Scotty finally makes repairs and you have engines firing again. Unfortunately they are still not quite repaired and they fire at a constant rate (that is, they are providing constant thrust) and can't be turned off. Explain the motion of your craft when the engines fire up again and as they are constantly firing.
THANK YOU!!!
