Question
A train starting from a railway station and moving with uniform acceleration attains a speed 40 \text{ km h}^{-1} in 10 \text{ minutes}. Find its acceleration.
Answer
Given:
Initial velocity (u) = 0 (since it starts from rest)
Final velocity (v) = 40 \text{ km/h} = 40 \times \frac{5}{18} = 11.11 \text{ m/s}
Time (t) = 10 \text{ min} = 10 \times 60 = 600 \text{ s}
Formula:
a = \frac{v - u}{t}
Calculation:
a = \frac{11.11 - 0}{600}a = 0.0185 \text{ m/s}^2
Answer: The acceleration is 0.0185 \text{ m/s}^2.
