Question

starting from A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km per hour in 10 minutes find its acceleration

Answer 1

Answer:

Acceleration of the train is 0.0185 m/s².

Answer 2

$\huge{\underline{\tt{\red{Answer-}}}}$

Acceleration of the train is 0.0185 m/s²

$\small{\underline{\tt{\blue{Given-}}}}$

Initial speed of the train, u = 0 km

Final speed of the train,$v = 40 km/h = \frac{5}{18} \times 40 = 11.11 m/s.$

Time taken = 10 minutes = 10 × 60 = 600 sec.

$\small{\underline{\tt{\blue{solution-}}}}$

$\implies a=\frac{v-u}{t}$

$\implies a=\frac{11.11-0}{600}\implies a=\frac{11.11}{600}\implies a=0.0185 \: m/s^2$
