Question

A train travels 6 meters in the first second of travel, 6 meters again during the second second of travel, and 6 meters again during the third second. Its acceleration is

A. 0 m/s^2
B. 6 m/s^2
C. 12 m/s^2
D. 18 m/s^2

Answer 1

The train's acceleration is 0 m/s^2.

Step-by-step explanation:

The train travels 6 meters in each second of travel. In the first second, it travels 6 meters, in the second second it travels an additional 6 meters, and in the third second, it again travels 6 meters. Since the displacement is the same for each second, the velocity remains constant, which means there is no acceleration. Therefore, the answer is A. 0 m/s^2.
