A train pulls out of a station at a speed of 7 m/s. 67 s after leaving the
station, the train is going 30 m/s. What is its acceleration?
To find the acceleration of the train, we will use the equation:
Acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is 7 m/s, the final velocity is 30 m/s, and the time is 67 s.
Substituting the given values into the formula:
Acceleration = (30 m/s - 7 m/s) / 67 s
Simplifying:
Acceleration = 23 m/s / 67 s
Now we can calculate the acceleration:
Acceleration ≈ 0.343 m/s²
Therefore, the acceleration of the train is approximately 0.343 m/s².
