A train starting from a railway station and moving with uniform acceleration attains a speed 40 km h-1 in 10 minutes. Find its acceleration. |
|
Answer» Initial speed of the train u = 0 = 40 x \(\frac{5}{18}\) = 11.11 m/s time = 10 min = 10 x 60 = 600 sec acceleration a = \(\frac{v-u}{t}\) = \(\frac{11.11-0}{600}\) = 0.0185 ms-2 ∴ acceleration of a train = 0.0185 ms-2. |
