Answer:
the acceleration of the train is 0.0185 m/s².
Step-by-step explanation:
First, we convert the speed to m/s:
40 km/h = 40 * 1000 m / 3600 s = 11.11 m/s
Next, we convert the time to seconds:
10 minutes = 10 * 60 s = 600 s
We use the formula of acceleration:
acceleration = Change in velocity/time
acceleration = (Final velocity - Initial velocity) / time
acceleration = (11.11 m/s - 0) / 600 s
acceleration = 0.0185 m/s²
Therefore, the acceleration of the train is 0.0185 m/s².
