Calculating Acceleration of the Train
Acceleration is the rate at which an object changes its velocity. In this case, we are given that a train starting from the Railway Station attains a speed of 21 m/s in one minute. We need to find the acceleration of the train.
Given data:
- Initial velocity (u) = 0 m/s (since the train starts from rest)
- Final velocity (v) = 21 m/s
- Time taken (t) = 1 minute = 60 seconds
Using the formula for acceleration:
Acceleration (a) = (v - u) / t
Substitute the values into the formula:
Acceleration (a) = (21 m/s - 0 m/s) / 60 s
Acceleration (a) = 21 m/s / 60 s
Acceleration (a) = 0.35 m/s²
Therefore, the acceleration of the train is 0.35 m/s².
Explanation:
- The train starts from rest, so the initial velocity is 0 m/s.
- The final velocity of the train after one minute is 21 m/s.
- Acceleration is calculated using the formula: acceleration = (final velocity - initial velocity) / time taken.
- By substituting the given values into the formula, we find that the acceleration of the train is 0.35 m/s².
- This means that the train's speed increases by 0.35 m/s every second.
