Final answer:
The car is traveling at a constant speed, which means that its acceleration is 0 m/s², and none of the given options are correct.
Step-by-step explanation:
The question asks to determine the acceleration of a car that is traveling east at a constant speed of 2000 m/s and arrives at its destination after 200 seconds. However, since the car is traveling at a constant speed, it means there is no acceleration because acceleration is defined as the rate of change of velocity. If the car's velocity does not change, its acceleration is 0 m/s². Therefore, none of the given options (a) 5 m/s², (b) 10 m/s², (c) 15 m/s², or (d) 20 m/s² is correct.
