Problem

A train starts from rest and accelerates uniformly at 0.5 m/s20.5\,\text{m/s}^2 until its speed reaches 15 m/s15\,\text{m/s}. It then continues to accelerate uniformly at 0.2 m/s20.2\,\text{m/s}^2 until its speed becomes 25 m/s25\,\text{m/s}. Calculate (i) the distance covered during the first stage, (ii) the distance covered during the second stage, (iii) the total distance travelled from the start till it reaches 25 m/s25\,\text{m/s}. a. (i) the distance covered during the first stage b. (ii) the distance covered during the second stage c. (iii) the total distance travelled from the start till it reaches 25 m/s25\,\text{m/s}
