A bullet train traveling at 2.5m/s, takes 30 minutes to get to the station. What was the train's acceleration in m/s^2?

Explanation:

Given that,

Initial speed of a train, u = 2.5 m/s

Finally, it reaches the station, v = 0 (at rest)

Time, t = 30 minutes = 1800 s

Acceleration is equal to the rate of change of velocity. So,

So, its acceleration is .

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
