Answer :
Final answer:
The acceleration vector when the car is accelerating is 2.00 m/s² horizontally, and during the constant velocity phase, the car's acceleration is C) 0 m/s².
Explanation:
To answer the student's question, we need to identify the correct acceleration vector during the car's acceleration phase. Since the car starts from rest and accelerates with a constant acceleration of 2.00 m/s² for 4.00 seconds, we know that this acceleration is in the direction of the car's motion. Assuming a standard convention where upwards and rightwards are the positive directions, and the car is moving horizontally (on a flat surface), the correct answer is (d) 2.00 m/s² horizontally. During the constant velocity phase that lasts for 12.0 seconds, the car's acceleration is (c) 0 m/s² because its velocity is not changing.
