Question

A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km/h in 10 minutes. Find its acceleration?

Answer 1

Initial velocity (u) = 0 km/h

Final velocity (v) = 40 km/h

Time (t) = 10 min = \(\frac{10}{60h}\) = \(\frac{1}{6h}\)

Acceleration (a) = \(\frac{v-u}{t}\)

\(\frac{40-0}{1}\) = 40 × 6

= 240 km/h
