Question

A train starting from a railway station and moving with uniform acceleration, attains a speed of 40 km/h in 10 minutes. Its acceleration is :

• A. 0.00185 m/s²
• B. 0.075 m/s²
• C. 0.0185 m/s²
• D. -0.0185 m/s²

Answer 1

The correct option is C

0.0185 m/s²

Here,

u = 0 , v = 40 Km/h = 11.11 m/s , t = 10 minutes = 600s

Using, a = $\frac{v-u}{t}$

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

a = 0.0185 $m/s^2$
